There was a large trail of destruction around here too, I would say if there had been a more proactive preventative approach it could have limited damage, not that people should have to, but the day after the riot here the streets were lines with police, they were everywhere, shop windows had been emptied or boarded or secured up (and torrential rain was a bit of a blessing), it a bit like opening the stable door after the horse had bolted, a very muted, barely visible presence the day of the actual riots.
I ended up in the midst (literally right in the middle) of two separate mobs of rioters, the second of which were mainly on bikes, bandanas over their faces, carrying weapons trying to smash their way into shops. I just tried to flatten myself into a bus shelter to hide until the police sirens approached and they scattered. It was terrifying, nothing to do with any political cause or message, just sheer lawlessness.
