I dont know the full details of the story, but the theory is there and it sounds like a good idea to me, although i dont think they should be free. theres always problems outside clubs at kicking out time, regardless of where in the country you are. And its more often than not the idiots who hang around late wanting a fight and to cause trouble. Get these people away as fast as possible and your half way there to solving the problem. Still, this is what the police should do to start with but the theory of getting them out the way as fast as possible is the right one. Although it shouldnt really have to get to this stage.
