Right, not sure if anyone's said this already, but here goes: I think all of you are overreacting slightly, ok, so Bluewater introduces a ban on hoodies, caps and threatening behaviour, so what? I see it as a pre-emptive measure, an option if you will, it's ridiculous seeing at as NO ONE is allowed to wear a hat or cover their face. I see, and I think Bluewater management and the police see it as an option to get rid of 'chavs' without argument. Obviously there will be a great deal of common sense involved (never thought I'd say that about the police) for example, if they see a young girl with parents wearing a hat, not causing any trouble, I'm sure she will be allowed to carry on.
The way you're all talking is as if this measure is some kind of Orwellian nightmare, , let's not overreact when there are far more important and, if you like, 'nanny-state' issues being ignored.
