I have felt for a long time, that something needs to be done to reduce the violence and protect the people who attend to enjoy themselves, which are of course the vast majority.
It seems akin to many demonstrations. It all starts off peacefully and wonderful and then it gets "infected" by the unruly mob, who have less chance of being apprehended with all the people around.
This year Scotland Yard made 454 arrests across the two days of the Bank Holiday street party, including 45 attacks on police and 88 knife-related incidents.
Metropolitan Police Federation chairman Ken Marsh claimed that rank-and-file officers “dread” the event, the biggest of its kind in Europe, in which they are treated as “professional punchbags”.
There are suggestions that the festival could be held in Hyde Park, an all ticket affair, where attendees are searched beforehand.
Ok, it won't be quite the same, but surely a better idea, that the revellers can revel, without the risk of being robbed and assaulted ?

About time we manned up and gave the great unwashed a bath at the same time.
There are always going to be those that go to cause trouble or commit crimes, but with the majority of people going to enjoy themselves then why change it?
Cos it's Notting hill and you'll be called racist if you say otherwise, it's just described as a good vibe.
Stop it or bomb it. Either or, I'm not arsed.
I don't like the Notting Hill Carnival, but that's irrelevant.
It's a waste of police time, seems to piss off the locals who it infringes upon and generally would've been banned long ago where it not for cultural sensitivities. (See the fall out from Lambeth council cancelling the Brixton event this year, and the response they got which seemed to centre around allegations of racism)
As for claims of racism, once again I'm gonna have to agree with GJ. A great example was the recent event in Brixton which was cancelled, and the amount of people who claimed The Met and Lambeth Council were racist for blocking it. It's very daft, but people still claim it sadly.
BTW - The Met have quite a good breakdown of what the arrests were for, and considering the type of event it's obvious that certain things are treated in a more lenient way due to resourcing. Plus, Sunday is supposedly the family day - what kind of family day sees 150 people get nicked?! It's also worth noting that the Met Police Federation have spoken out against it too, stating that it's an officer safety issue too. I'd much rather see the police using their limited resources more wisely, and that doesn't include Notting Hill Carnival.
Mind you, it shows how "used to it" we've become, if some think it should continue in its' present form, because 15 people getting stabbed is not important enough, to want to do something about it to protect the innocent.
Perhaps, we'll wait for the first murder ?
Say it is roughly the same, which I'm guessing you're expecting if there's 1,000,000 in one location. Now the second largest city - by population - in the UK is Birmingham, at 1,100,000. Are you saying it's an acceptable expectation for the locals (and the police) to have to deal with crime equatable to Birmingham's over a weekend in one small area which is contained in a much larger city?
Whether or not it's comparable to another city with a similar population is - in my opinion - not really relevant. It requires a ridiculous amount of policing, results in over 1 arrest every 6 minutes, has seen 8 police officers sent to hospital, 5 youths nearly losing their lives, 16 individuals being sexually assaulted and 90 people being caught wandering about with weapons. This is supposed to be a carnival - something fun and friendly - but it's not, is it?
There will always be arrests at any major event that attracts those kind of numbers .
Thank you for making a brilliant - if unintended - point though: when clubs, bars and pubs get the kind of reputation that the Notting Hill Carnival has, they get their licenses revoked and are shut down. That's precisely my point too, I'm sure we can all list places that have closed down - personally I can think of 3 off the top of my head - for the very reasons that Notting Hill Carnival has become known for.. but on an absolutely tiny scale in comparison.
I'm not asking all street festivals to be banned, that would be like asking for all clubs, bars and pubs to be banned. I'm asking for one that is synonymous with trouble, violence and crime, and places an incredible burden on the surrounding area, to be shut down: just like we would a club, bar or pub.
