Right... so no causes, no context, right?
The fact that almost 50% of young people in inner city London are unemployed with little or not hope for the future has nothing to do with it?
The 300+ deaths in police custody in the last three decades has nothing to do with it?
The shooting and apparent coverup of the man in London has nothing to do with it?
The truth is, London is a bit of a Victorian shithole. You have huge numbers of disaffected, poor, unemployed people living in squalor, while their public services are being cut to pay for bailouts for bankers - who continue to award themselves millions in bonuses.
I'm sorry, but it's just absurd to say just say it's 'feral youth'. Why so many youth at the same time? Why so many youths willing to do this? Why so much anger? Happy communities don't riot. Do you think if we lived in a healthier, happier society with more equality and less poverty, with job opportunities, with a government which represents the interest of the public well-being at large, rather than the feral elite and the richest - do you think there would be so many people rioting?
People commit these sorts of crimes when they have nothing to lose. Do young people who have a good job and live in a nice house in a crime-free neighbourhood go out and riot? Of course not.
The violence is not justified, but neither is it unexpected or 'random criminality'.
