Well how marvelous they they have been kicked "out", to no place in particular, where everyone can be confident that they will diligently refrain from doing anything they have been "banned" from doing.
I doubt that anyone is under such a naive illusion that they will instantly become good and productive people. As I stated in my post #3, they will of course merely start up again somewhere else. The good thing, however, is that now the entire U.K. is aware of them and will give them a very cool reception wherever they might go. The Merseyside police will undoubtedly bring the police in their new community up to speed on their nefarious acts, and they will be under a microscope continuously. Two of the devil-spawn are already in prison, and the rest will likely follow in short order.
I'm glad that this ASBO was made, however, as these idiots will likely not be bright enough to abide by it and will quickly find themselves in violation. This gives local law enforcement a tool to work with that they didn't have before.
