The ASBO is being replaced by the gang injunction. No longer can you have criminal offences hand-crafted for you personally, like a criminal offence of staring out the window, going near a river, or standing in the garden in your pants.
However, if you’re a member of a group of three or more people who all wear an instance of the same class of clothing, and threaten violence, then you could have a gang injunction placed on you. There is surely a loophole here for nudist gangs, and I look forward with interest to the first test case.
