It's been interesting watching the events here in Manchester over the last few days. Right before the riot in the city centre it was all very normal, very muted police presence around town. The small groups of potential yobs were quite obvious hanging around waiting for something to kick off they could jump on the bandwagon with. I got caught up in two rampaging mobs, initially when a load ran when the shout went up something was kicking off and then later when I was trying to get a bus out of town when a load of them came charging through with weapons trying to smash their way into shops then when all the sirens started they moved on. I have to say it petrified me, especially the second incident and moreso as there were no visible police despite being in a very busy area of town - last night and even tonight there were loads of them in sight.
Last night town was absolutely flanked by police, they were all over town in large numbers. A suspicious looking group passed work followed by a few police vans, they were targetting people wearing hoods, hats etc... Ok, the torrential rain can but have helped but it was a huge disincentive, especially to small groups looking for trouble to jooin and the widespread police presence would have made it, in my opinion, much harder for them to group together and have police free windows in which to wreak havoc.
I've seen similar tactics used for policing big football matches. Protests different as more containable (the riot police literally fenced the anti racist/anti facist clash in) an incident like the Rangers match was difficult due to sheer scale of numbers. I can't help but wonder if the same large scale pre-trouble police presence had been used on Tuesday night could have made quite a difference, it didn't take a genius to predict it was likely to kick off.
Salford I'd say different, a far more open and difficult area to control (albeit - not that they seemed to show it on the news - right next to a large police station) and not very nice area there (right by the Brasshandles broad daylight gang execution a few years ago).
