So we can't punish them in a harsh way, way can't give them two chances and then say enough is enough, we can't give the victims any say in what happens, we can't treat them like the scum they are, we can't prevent crime because parents, teachers and police aren't allowed to dicipline children, poor people are given carte blanche to procreate as much as they like knowing the cost will be borne by the state, and lets be honest, between the poor and immigrants that's where most violent crime occurs, we allow people to drink themselves into a stupor, attack others and walk free.
The zero tolerance against knife crime is about as effective as an ashtray on a motorcycle, gangs are allowed to get away with not grassing on fellow gang members (torturing names out of gang members is not something I'm opposed to), we allow rapists, pedos and murderers to grace the streets with their presence after serving several years in a relatively cushy environment (regardless of what you think, they have it easy compared to say china or thailand) at the expense of the victims.
What are we to do then?
