Lets be fair to the rozzers here, (and I am not talking about the met who are a special case) they have a difficult job to do and they are never there when you want them but always on your case when you don't. The law needs to be flexible and I think notwithstanding the ridiculous burden that Government piles on with silly and ineffective laws the basic principle is there that they can find a reason to arrest you if they want to, but if you are not causing any trouble they won't. Sometimes it is necessary to find an excuse to get somebody of the streets for something they could not otherwise pin on them. Does anyone seriously think that these guys were just out for a bit of bushcraft?
