At one point you have to think of the victims too. For 20 repeat offenses recorded, there has been hundreds of beat-ups. I met a guy who said he’s been 200 times (his estimate) in custody between 13 and 18. He had only been condemned once, at 19. He bragged to me about how many French people he bullied, including locking up a fat kid in a basement for 3 weeks. You have to think of the victims.
Again, look at repeat offenses of usual criminals in newspapers, and remind yourself that they have been presumed innocent to the extreme and only condemned for cases which have been extensively proven, where victims dared to talk, knowing he has a condemnation rate of less that 0,5% per arrest.
