The biggest problem is that there's nothing that can be done legally until they break the law in a way that clearly puts someone at risk. If the police come to the door and they don't answer, we don't want the police to kick the door down because the neighbor's heard shouting. The idea that the city could have people involuntarily committed for "acting like jerks" is terrifying, and sadly that is perhaps the only way to modify behavior: by providing an environment that encourages good behavior. That doesn't exist in their home, in an institution, and certainly not in prison.

We called the police on our neighbors who had been outside screaming at each other for nearly an hour, and nearly as soon as they went indoors, we heard a loud boom that sounded a lot like a gun shot. The police arrived, knocked on the door, and when they didn't answer just drove away. Nothing had happened, fortunately.
