Except for the last one in your list, the others are quality of life problems. I have no problem if police interfere with either. Even the last one, is at best borderline. If there is a weirdo making machine guns in my neighborhood and I have kids, I sure as hell want police to interfere.
That works in theory, until the police are overrun with things they don't specialize in and don't have the officers to handle the day to day plus illegal arms dealers.
