Although they are commonly described as postcode wars, in many cases the disputes can be far more localised. "If you fall out with someone on a particular street, then it's not just the next postcode, even the people on the very next street will have a beef with them," adds Reggie. "It doesn't matter where they are, only that they are somewhere different to where you are. You get people saying, Oh, someone from that street over there did what? Right, next time we get hold of one of them we are going to make them pay'. They think we have got to back him up' or we have got to get revenge' and that's how it starts."
