I'm not sure if "nice" is a logical word to use in this context. https://en.wikipedia.org/wiki/Broken_windows_theory

Be assured it isn't "just" drug addicts but increasingly profit minded criminals and misguided teenagers, 'etc. They smash the windows anyhow and occasionally set things on fire for kicks.

And there are more and more organized and semi-organized groups.

I can see some kids getting in on the action, but unhoused neighbor bashing in a car window in plain view is common where I’m at (Seattle). The only time I’ve seen it done otherwise was with Kia Boyz in a Fred myer parking lot, but I think they were just doing random things without much real thought (let’s steal some cars, and then go use them to try to snatch purses and bash windows at a busy Fred Myer on a Sunday afternoon).
