I looked it up, and CSOs are actually part of the police, which is the first problem. The second problem is they can't issue fines. I don't think someone should be arrested for playing loud music on a balcony, I don't believe that's a proportional response outside of the most dire circumstances involving severe sensory processing disorders. But I do think they should be fined a certain percentage of their income and assets which increases based on their tax bracket. And I do think that's a convincing deterrent. "How many grand is that song worth to you? Because if you keep playing it, you're gonna have to pay up."
