Considering what British city centers are like around chuck-out time, why can't we have some police out on foot patrol around that time? It's not that the areas around the lager palaces are no-go zones, but then I'm not that comfortable around lagered-up yoof either.
With CCTV cameras you have a better chance of arresting a drunk hool after he has committed an assault, but with police out they will think twice before picking an argument. Cameras might help solve crime, but proper policing is preventing crime before it occurs. Besides, I don't appreciate having my every movement stored on tape.
