That sux, even if it wasn't on camera I bet the cameras around will help the cops narrow down who it was. Most criminals are pretty stupid (hence they don't have real jobs) and the usual suspects are often well know to Police as they keep taking them to court and the judges keep letting them go.

It's like fishing, anything under 18 they have to throw back and rearrest once they mature, lucky for us most aren't smart enough to work out how not to get caught.
