Criminal Justice and Immigration Bill

I hope that the noble Lord will forgive me, but I am trying to understand this. The nearest I can get to it is a conditional discharge. I speak as a former magistrate. Someone who receives a conditional discharge must have committed an offence. The aim of giving a conditional discharge is to try to ensure that the offender does not do something that is likely to result in them receiving a real sentence. Are we talking about there not being enough police to go into an area if they hear about problems and wait there until they can arrest someone for an offence? I find this very difficult to understand. Perhaps the Minister can describe the conditions that he has experienced in north London that would merit this measure.
