Why does apartment management expect you to call the police over every tenant incident?

I think the answer is - because they're lazy and want you to do their dirty work for them. I quite frankly, am not going to call the police over noise complaints because I think management should do something about that. Police should only be called when violence or tenants who get aggressive.

Not because of noise, I just think it's management dumping responsibility onto you when they're the ones with the power to evict people.
