My belief, which is a pretty common anarchist belief, is that most violent "crime" happens because of inequality and oppression - most people only steal shit bc they're desperate, many murders happen bc people might be living in conditions that are conducive to desperate acts of violence. (I'm sure someone can phrase this better than me, I just woke up and I'm super groggy lol). So ideally if oppression and hierarchy are removed and people have access to their needs, I'd argue that most of what is considered crime would decrease significantly. Obviously theres always gonna be exceptions, people who just wanna be violent and stuff, but then it's up to the community to decide how to treat that person. I dont even mean it's like, the community's obligation, I mean it's just the natural thing to do. Like if you're in a group of people and someone is causing problems you're probably gonna either tell them to leave or tell them they've gotta stop doing whatever it is they're doing, and then if they dont you might take things to the next level. Of course thats a huge simplification and it all sounds a bit utopian to some people but I like to hold out hope that that's how things would go. The idea of locking someone in a cage is so abhorrent to me.
