The thing is in London there are some pretty decent shops selling "Genuine Designer" clothes and clever "electronic" gadgets. In Birmingham they've only really got a few pound shops and takeaways. So as soon as everyone gets a free golf umbrella and a can of Tizer they'll all be boing boinging back to the squats.
In fact, the police should issue every hoody with a voucher for the pound shop and set up free Shandy bass dispensers at every high street. That should confuse them enough to go back to bed.
