I can't believe London's Mayor Boris Johnston's statement to "Walk on by" if you see a crime. We have 120,000 police officers in the UK and millions of people. If we depend on the police to deal with the thugs we should just give up now. The government add more and more human rights to assist the criminals and give less protection to the law abiding.

I am not saying we should endanger our own lives, but we should not stand by and allow this element of society to take control. Political correctness has gone mad in this country. A 12 year old has just been charged today with the murder of a 71 year lady and two members of her family are in a critical condition thanks to him. Yes yes I know there are decent youths in the country, but there are a lot that aren't. A lot of little bastards need to be locked up for a very long time.

Mr Johnson said peole should move away when they spot trouble and not get involved. Mr Johnson's warning comes in contrast to his call last year to people to "take a risk" and tackle trouble-making thugs, saying the chances of being stabbed in retaliation for challenging a yob were ``microscopic''.

So far this year 17 youngsters have died in violent clashes in London alone, exactly the same number as this time last year. New figures showed the number of school children treated for stab wounds has doubled in the last five years.

The Hospital Episodes Statistics show admissions for under-16s have risen by 88 per cent, from 95 in 2003 to 179 last year.Adult admissions for stab wounds increased from 3,745 to 4,786.
