When will it end? It won't. You would think people would become shocked enough that something would change, but it only gets worse. people are so desensitized, they just think 'as long as it's not me' well, one day it will be, or someone you care about. I promise.

Max Murphy, London, england

There is no respect for human life in this country, decent young people like Jimmy were let down by this country that produced mindless, wasteful and destructive beings like Jimmy's killer.

These people have had enough chances, they need to learn respect and the reality of their actions.

Al, Glasgow,

This is a deeply tragic case and I feel great sympathy for you. The government needs to come down hard on crimes like this to prevent any more upstanding and decent young men like your son being victimised by these brainless apes.

lee, colchester, england

At the moment there are next to no consequences a violent yob need fear. I say what the Government has to do is GOVERN... Unless real punishment for such violent crime is meted out on a regular basis...! - every time...!! - then this senseless scourge of our inner-citiy youth can only grow worse...!

John Jay, Walton on Thames, UK

Dear Barry, Margaret and children

I just don't know what to say. I am deeply sorry for you and losing a son with his life ahead of him is just so sad.

I have 2 wonderful sons and my heart is broken now at your loss.

May God give you strength.

I worked with the Mizen family children and this is just senseless. I last worked with them about 10 years ago, and to this day I recall many happy memories of the whole family. All I can say is that the love that the family has for one another will carry them through this.

Paul, Norwich, UK

So sad my heart goes out to his brave family!! He was a close friend of my cousin george he went to a party with him just on friday night it's terrible! I just hope they catch this person and throw away the key!!!!

JADE RULTON, SIDCUP, ENGLAND

Interesting to see that the Police have now said their chief suspect is Turkish.

Perhaps that will go some way to softening the blow of those who thought he was black.

Mike Shingleton, London,

Thank you to the Mizen family for showing such humanity and grace in the face of their appalling loss.

I wish I could agree with those of you that think that the death penalty would fix this. But look at the US, or African or Middle Eastern countries which have it. The solution is harder sadly.

EF, NYC,

Later that evening, not 5 miles away, my daughter aged 14 was threatened with a knife. An older teen produced a knife while others surrounded her, opened the blade halfway & stated "I could slice you up with this!" Police failed to find the knife after stopping the girl & said nothing could be done.

Jordan, Charlton, England

We're told that in a ciivilised society capital punishment is not an option. In the uncivilised 60s people were aghast when homicides in England and Wales reached 300 per yr. Something needed to be done so the politicians of the day abolished capital punishment, result nearly 900 homicides per yr

John, London,

This is such a horrible story. It gave me shivers down my spine. I can't imagine this happening to my daughter. My greatest sympathy for the family. This boy is lucky he didn't do this to my daughter, he'd be dead too and it wouldn't be pretty.

Matthew Lipscomb, Montreal, Canada

''Softly,softly'' I hear the government say....where has this got the country? Society in LDN is not what it used to be and until the youth are disciplined appropriately this will only continue.

It's disgusting and agree with many readers; it makes me feel sick.

KL, Tokyo, Japan

Again this is happening its a totally waste of a good mans life and our hearts and thoughts and prayers go to this family and more so it wasa senseless thing to do and now another young persons funeral ..god bless you ..

Lynne, forest hill london , united kingdom

I don't think it's unfair to guess the attacker was non-white. But non-white covers a broad spectrum of 'ethnic minorities' and it's often not easy to tell for certain what race a person is. How should a 'black' person feel if the press says he's black and he turned out to be a really dark asian?

Nichole, London, UK

How much longer will the government sit around and do NOTHING about this sort of violent crime? In isolation this story is hugely distressing and my thoughts are with his family but it's a sad and undeniable truth that this kind of brutality has permeated into modern British life.

Daniel, Bangor, Wales

Poor boy. God rest him.

Carl, London, UK

All I can say about this apart from offering sympathy to this poor lads family is ask when do we get a description of the attacker there were many witnesses so surely they can come up with more than a male youth!

John, London, England

My thoughts to the family and friends of Jimmy... this is so very sad. There is obviously a real sense of fear and anger about this and other attacks. I may not have influence over the perpatraitors involved but I can be more pro-active in making the world a safer, more respectful place to be.

Marc, Cornwall, UK

What a terrible, violent waste of an innocent young life that held so much potential. There is no point in others calling for capital punishment in this case, as it is obvious the perpetrator is a youth and the law does not hang youths. I support capital punishment unlike our cowardly politicians

AG, Wimbledon,

what is the world coming to?edcent folk are hounded and killed,the evil laugh and prevail.i deapair for my children.WHEN I WAS A CHILD I WAS TAUGHT THAT GOOD WINS EVIL,now im not sure.everyone is angry,looking for a fight ,ready to defend anyone whether right or wrong.I DESPAIR!

RSMANN, west brom, west mids

It is time for capital punishment to be reinstated. Pleading humanity for these criminals does NOT protect those who behave responsibly in society and deserve an equal right to live free from such atrocities. Stop the uncertainty of palm tree justice with the resounding death penalty as a deterrence

Darren, Sheffield, United Kingdom

An absolute tradegy, yet another promising and popular individual is cut down, and for what reason, because some idiot fancied a bit of gratuitous violence. The sooner that capital punishment is put back in the public arena for a free vote the better. A society of you can't touch me has been created

Geoff Lusk, Margueron, France

Was the killer Black? Simple question simple -answer. The entire police force of London know, the entire Cabinet and many of the Press, and the family of the victim? Lots of people are asking it? Why can't we be told? Whatever the motivations of those that ask - millions are asking.

Sophie, London, UK

absoloutley appaling incident. Society needs to change.
comments on here reckon the murderer is not white or is an immigrant. There are loads of uk white teens/young men who are vile foul and violent. The same for all colours/nationalities. Bad people are bad due to being human, not ethnicity

david, london, uk

In all the other cases of youth murder to which this is being compared, the police have issued a description of the criminal. It is not the case that they refuse to mention skin-colour on politically-correct grounds. I am sure that if the police are issuing a minimal description, they have a reason.

DB, London, UK

For example, whilst waiting for a key witness to come forward, it may well be better not to run the risk of 'polluting' his evidence with information he could pick up from the media and then, as happens frequently, embed within his perceived memory, running the risk of invalidating his testimony.

DB, London, UK

To help trace a witness the police describe him as white middle-aged. Therefore it must help trace the killer to state his colour also.

T Newton, London, Mx

The person to blame for this is the person that dit it. He must be caught and tried. Deppest sympathy to the victims family

Chappie, aberdeen, uk

Disgusting. I feel physically sick when I think of yet another young man's life being taken away without a second thought, over another sick act of random violence fueled by lowlife scum; attempting to appease themselves by attacking innocent young people for no other reason than to fuel their ego.

DT, SE, London,

Please stop with the racist comments, they are not helpful nor needed. May the boy rest in peace and may we all,regardles of race colour or creed, live in it. The colour of your skin has nothing NOTHING to do with whether you are a bad person or not. My sincere condolences.

Adam, Valencia, spain

Awfully sad, my thoughts are with the parents and the family, you raised a lovely boy there.
My heart goes out to you

Jude, Abergavenny, Wales

What does this say about today's British society when another young innocent person loses their life like this?
Life is precious and to protect that we need to have tough measures like using our military and a zero tolerance approach on the streets. Sadly, the Human Rights Act gets in the way.

Paul, West Midlands,

Well. Why no description of the person alleged to have done this?

john, norwich,

I'm sickened by this murder.
I'm also sickened by those who are using it for their own political ends.
What have we come to?

Mike S, Walthamstow,

I have never believed in capital punishment but hearing of the murder of this fine upstanding young man I believe we should think again. Too many mindless thugs are roaming our streets now thanks to this appalling Government. My thoughts go out to his family.

sophie smith, london,

All of us are saddened to hear what has happened to Jimmy. And everyone of us keeps enough is enough. But I don't think, we are doing enough to help the teenagers of London. I really think the time has come for many parents of London to proper discipline their children and bring up with manners.

Bashkim Krasniqi, Lewisham , England

The murderer will probably get a minimum 15 years and the judge will say this will send out a clear message to others.....yep thats right but not the message these judges (who live well away from violence) think they are sending i.e. tough quite the opposite....weak. Murder should be life in prison

Pete, Yorkshire,

What is happening to our country where the precious lives of our children are ended so brutally by other children? I can't imagine the pain they are going through. Evil happens when good people remain silent. If anyone knows something have the courage to speak up, please. You are all in my prayers.

F Barratt, Chesterfield, Derbyshire

There are an awful lot of comments urging the death penalty or the trying of the perpetrator as a adult--quite American-like sentiments and shocking to a regular reader of these things, which frequently lay nearly every species of societal ill at the doorstep of your cousins across the pond.

Jeffrey, New York,

Someone PLEASE explain something to me.We really need everyone to look out for the killer of this lovely Guy.To assist us we need the fullest description possible,obviously.So WHY is there no mention of the Sispects colour?...If he is White with Ginger hair or Black and tall or Asiatic LET US KNOW!!

Tony, Welling,Kent, England

A.N. - stopping welfare and abortion merely results in more people with even more reduced means, which may lead to more tragic events like this. Jimmy sounds like a wonderful young man, someone brave and decent. We should all wish to have the courage of conviction he clearly possessed. Tragic loss

VB, Bristol,

So why no description (white, black or asian) of the wanted youth - is this police censorship?

Stephen, London, England

Yet another tragic loss, how many youngesters have to be murdered before something is done! The government think nothing of putting millions of pounds into war abroad, yet what they should be doing is putting millions into the war that is happening every day to our young children!!!!

Pauline Facer, Bexleyheath,

This is very sad.
When the police catch the murderer, and let's hope that's very soon, will the judges give him a fitting punishment for this appalling crime?

Dilip Dhokia, Bradford, UK

Once again, a good wholesome youth is killed by a scum with no morals. This is usually coupled with poor education and upbringing. Once again a bereaved mother who feels some compassion for the parents of the killer. Capital punishment is on everyones lips once again. It feels justified once again.

DR, Bristol, England

For murderers there should be no prison. Why retain your right to life when you have deprived another of theirs? The death penalty is the only deterrent that will work, since anything else sees the murderer get off more lightly than their victim.

Mike, Liverpool,

I cried when I read this story. Another innocent victim murdered on our streets. What a lovely family they are. Jimmy was just starting out in life and had so much to look forward to, so cruelly taken from him.. RIP Jimmy.

paulinehoran, ashford , kent

jimmy was the best
best luck in the afterlife jimmy
9/5/1992-10/5/2008

sarah brundritt, London, england

What a terrible loss. Yet another depressing example of how aggressive, mindless thugs who contribute nothing to our society, and the parents who fail in their responsibilities, are ruining it for the (seeming minority now) who do.

NS, London,

May he rest in peace and God bless his family and give them strength to get through this terrible time. Boris show your respect for this brave lad and lead a drive to get him the GC. He stood for decency and died for it. Londoners rally around him. Shame these thugs before it's too late.

Patrick Corden, Los Angeles, USA

The parish really is in shock - Jimmy was a remarkable & much-loved young man: a credit to his parents & an asset to society. I very much hope that the killer is caught & brought to justice soon - such a senseless & evil act must be punished.

Xanthe, London,

40 years minimum with no parole will put a stop to this .

Nick Dixon, Sutton Coldfield, England

It sound like you all should institue a handgun ban.

Mike, Scottvellie, USA

Ridiculous with a murderer on the loose the police description is of a male youth. That fits all young males between 14-18 at least in London.

Richard K, Nottingham,

A good innocent lad is dead - surely now enough is enough? Capital and corporal punishment should be re-introduced.

Will the namby pamby PC brigade listen? Unlikely, but you need some drastic action to clear such vermin off your streets once and for all!

Badger your MP's - this is terrorism!!

Terry, Bagneres, France

I lived in Lee. My neighbour worked for the police service, while her 15 year old son ran riot. " I dont mind him having a couple of beers" was her comment when I tried to complain about one of his all night parties. Blame the parents and put them on trial too when you catch this murderer.

Linda, London, England

Until the law is changed and the power taken away from the human rights lawyers and given back to the Police nothing will change. I admire Boris for trying but it will make little difference.
Bring back parental discipline and re enable the teachers and police to enact theirs and things will change

Andy Murray, reading, uk

This is very sad . But these killings will continue unless deterents are put in place. Murderers are aware that in a few years time they will released from prison and yet the family of this young man will take all this sadness with them to their grave. For murder you should die in prison.

Frank, Derby, England

JFK from Marbella, I too left London with my then 9 year old son for the same reason. I felt that London wasn't a safe place for my son to grow up in, not so much the accesss to drink and drugs, more the street gangs, regular muggings and unprovoked crime.

Irving, madrid, spain

I'm so tired of reading about innocent people being hurt or murdered by those who have no morals. This young man would undoubtedly have grown up to be someone who contributed to society, produced good work in some field or other and made a good nieghbour, husband, father. What a loss to us all.

Zoe, London,

Syd Dernley and Harry Allen, where are you now Britain needs you again ? This kind of horror illustrates as nothing else can that the abolition of hanging was the work of criminal loving liberals who care not a fig for the victims nor their grief stricken survivors.

Megan, Lillington,

Although the numbers are still relatively low, the fact that something so petty as a disagreement in a bakery can result in loss of life is appalling.

In 2 years I'll be at a point where I can contemplate emigrating. If things are the same I'm off - voting with my feet.

Richard, London, England

It sounds like something out of a movie.These aggressive kids really do re-enact what they see on a DVD and that's the problem.The justice system and the parental control are skewed towards forgiving these sick kids.
I know that I am repeating a well worn phrase' PUT A STOP TO IT!'
Zero tolerance.

Alex, London,

We are not prepared to meet such violent people- we are not brought up with it. Better to avoid trouble and live.People do not have the upbringing these days and do not care what they do
But he was not just "trying to be brave" he was brave - and paid the ultimate price. I hope the killer is found

andrew, London, UK

Stop the politically correct nonsense. Stop the welfare state, stop abortion and start introducing policies that promote the families and keep them together. Bring back respect and discipline in schools. Perhaps some level of decency will then return to this country.

A.N, London, UK

I feel sick to my core with such mindless violence. The saddest thing is that is becoming the 'norm'.

From all accounts, Jimmy was a credit to his family and though not on a par with their unending grief, I am terribly sad.

Lucy McDermott, Maidstone, UK

what a sin...

that nowadays news reports cannot include a description of the scum on the run

It would make it easier for parents to recognise the evil in their homes

Pater May, Barcelona, Spain

If someone takes a life, they should pay with their own - not to act as as some stupid deterrent to others, but to ensure the scum that think this kind of behaviour is a suitable way of life never have the opportunity to take a second life.

Alex, London,

Here we are AGAIN another senless murder committed by some low life who has no fear of punishment whatsoever in a country that has a PM and Government who keep telling everyone that it is only the fear of crime that is the problem and that crime figures are lower than ever and we have more police?

keithw, Wirral, UK

"Would making it illegal to sip lager while sat on a tube train have saved this kid's life? "

Always some moron trying to point the finger in the wrong place at the wrong person - this tragedy is not down to our mayor, it is down to the scum that did it and his equally scummy family.

Alex, London,

Poor boy. Why wont our government do anything about this culture of violence, instead of just paying us lip service?

Amy, Canterbury,

As a Brit living in the U.S. I urge people to not go down the slippery slope of the death penalty. It is NOT deterrent. But yes. Life should mean life.

This is such a tragedy, but we must start to tackle what's wrong with our society, repair that, not take punitive measurements when it's too late

Lindsey Murray, SF, U.S.

As " white youths/Yobs " are always clearly stated in reports of attacks , why is the race of this attacker not stated ?? -- Is it because of unfair Political Correctness ?

Jasper, guildford, england

Jimmy is a worthy candidate for a posthumous George Medal.....
Long may we have people like him prepared to stand up for others.
Crime can be reduced by,;
reducing buracracy and putting more police on the streets, and, by longer sentences meaning once caught they are unable to harm us again.

micky, london, england

It does not take money to raise a child with manners and respect! As for the French, they make it an offence to not help 'a person in danger'. Hence, the 'villain' knows that someone will step in.

My deepest sympathy to Jimmy's family.

Chantal, Perpignan, France

Time for life to mean life.

Julian, London / Singapore, UK / Singapore

Whatever the age of the perpetrator, they should be prosecuted as an adult and dealt with accordingly. If those in power still shy away from capital punishment, despite the wishes of the electorate, then life should mean just that.
Take away a life and you should lose your own.

Paul Howarth, Messines, Portugal

I'm fed up with this. Its so predictable, violent and, above all, pointless. The offender should go to jail for life. Not ten or twenty years- life. The more people like this are taken of the street the safer it will be for everyone else.

simon, london,

This boy sounds like a wonderful citizen who was doing exactly what I would have done in the same situation. I hope the parents of the thug involved hang their heads in shame that they are responsible for letting something vile into the world. If we united and fought back, they can't kill us all.

Kate, Brackley, UK

Incredibly sad story

Suzanne, Wigan,

But of course have not people listened to the Home Sec. Crime is coming down - NOT TO WORRY - like Ms ???. who has police protection and a stab jacket when she goes out in broad daylight.
Incidentally did she pay VAT on the stab jacket? BET NOT.

M. Cawdery, Portadown, Co. UK, EU.

Decent people like Mr and Mrs Mizen have done a fine job bringing their children up- but many parents are failing in their duties as parents in Lewisham . There is a definite evil and spiteful streak amongst a small group and more resources need deploying against the CAUSES and symptoms of it.

Rob Ward, Lee, UK

We need straight talking and action now. Proper sentences for breaking the law. Give police the power to stop who they want, when they want and remove the cloak of political correctness from their shoulders. Target people who are a genuine stain on society. Stop this pampering approach to scum.

Ben, London, UK

We definately need some new laws being brought in. I have two young children growing up and i wonder wether it is actually safe to raise them in this country now. Being UK born and bred i always thought it would be a safer place, but for the past few years many incidents have had me worried.

Natasha, Colne, UK

ITs time new mayor Mr Johnson listen and decide to favour law abiding citizens of London and protect them.This may mean taking side of law abiding residents but thats what is needed and no sympathy for violence makers at all. What do you say MR Johnson, do u agree or not? Give full powers to police.

jon sangtani, london, london

I blame the parents and the government.
It looks like labour, in so many areas around the country have BRED the poor just for their VOTE.
Allowing them to be the mindless scum that many of the younger ones are.
Were they not so thick, labour would be out of a vote.
Blame labour, they ARE to blame.

Sean Hamerton, York, England.

Harsh punishment on its own is not the answer. Behaviour like this is a result of what is in the heads of these people and it is their parents who have reneged on their responsibilities to raise these people properly and society which has allowed them to get away with it.

David Jones, Loughborough, UK

Boris, as Bahaddur says, this is why we elected you. Many of us have teenage sons and although we can't hold you directly responsible for the safety of all of them we did elect you to ACT and sort out this violence that defines London. From yobs with their rap music on buses to this savagery. ACT!

Paul , London,

These tragic murders will continue until drastic action is taken. There is no effective deterrent and too many youths no know fear. They see time in prison as something to be proud of and don't value life at all. I now think the only way to stop this culture is a return to the death penalty.

Ros, London,

We need to change the law so that the penalty for murder is that the perpetrator is given a lethal injection and, if they are under 18, their parents can be imprisoned and also sued (into bankruptcy) by thebereaved family. That would make all involved take responsibility for their actions

James Smith, Nottingham, England

"Do not confront violent people unless a professional".
Dear me. This was a young man not a little girl. Clearly, brought up with a good sense of right and wrong and prepared to defend others, especially women in the shop. I doubt he had much time to think about the possible consequences.

tm, Herts, England

"Do not confront violent people unless a professional" ...if everyone acted like that and let mindless violent idiots get away with terrorising the ocmmunity then the world would be a very sad and much m place: this young man was doing exactly the right thing: standing up to the yobs. A tragic loss.

Joseph H, Madrid,

My 4 year old boy and wife were in the shop just 20 mins before this incident to buy ginger bread for h...a chill goes through my spine to even think if we were there a little later...My heart goes out for the family and friends..Boris thats why we elected you now get on with the job...

Bahaddur, Lee, UK

I feel heart broken for this poor family who have lost their beautiful son and brother.
We left London 10 years ago with our children then aged 8 and 9 because I believed it was no longer the great place that I had grown up in.
Zero tolerance is what they now need to make the streets safe again.

JFK, Marbella, Spain

its terrible, where he was killed is at the end of my road, and I often visit the same bakery. I had met him several times as well, its a tragic loss of life, and is having a terrible knock on efect on the community.

Liam Biggane, lee, England

My sympathy to the victim and his family.

It's a shame that the initial incident was able to escalate so quickly and that he became involved.

Sounds horrific for all involved.

Matt Langley, Crawley, UK

Do not confront violent people unless a professional.

caroline, Manchester, UK

When are we going do something ? The Government says crime is down but violent crime is not. There is plenty that could be done with a bit of bottle. Zero tolerance like NYC . Take kids into care when parenting is poor. Make victims more important than thugs rights.ENOUGH!

Chuck, Plymouth, UK

Would making it illegal to sip lager while sat on a tube train have saved this kid's life? I fear that unless real, drastic measures are taken in London, and not soundbite politics, this sort of incident will continue to become more common. A visible police presence would be a start..

Simon Holly, LonDon UK,

labour pro-feminist polices are to blame for this. The power of the man/father in the relationship has gone to discipline the kids and the kids are a law to themselves. It's time the father was given the rights to discipline their kids and have more rights in the relationship.

Raj Kumar, London, uk

Another mindless killing, and another family mourning the loss of a loved one. When will Governments and parents realise that this continuation of violence is destroying our youth.

Michael Evans, Plymouth, UK

There is no positive result for society of giving young adults freedom from responsibility and punishment. If it means the return of capital punishment, then so be it, but something must be done to ensure that citizens are able to live free of fear. We must reverse the degeneration of society.

Paul Flannery, Glasgow,
