Scientists and researchers have also been analysing riot footage in the city [Birmingham], hoping to learn more about the way crowds behave so preventative measures can be adopted.This sounds like pretty much the only sensible response I have read about so far.
Dr Patrick Tissington, associate dean of business partnerships at Aston University, viewed footage of an attack on a sweet shop in Birmingham.
It was targeted during the first wave of disorder on 8 August, in the city centre.
The footage shows one or two young men trying to smash the shop's window before others join as a crowd watches.
And you learned that ...
Dr Tissington said: "When one person goes at it, several others join in because it's now been established it's OK to do that because someone is doing that and no one is stepping in to stop them."
A message for the Police: get in there, as hard as necessary, when the first one starts and nip it in the bud. If you stand back and watch it all happen (and still no-one has explained why you did), then the disorder will increase exponentially, until it is out of control.
It's not rocket surgery.
