Years ago, someone broke into my neighbor's home through an unlocked window. MPD wouldn't take a report because it was not "breaking" and entering, and the guy didn't steal anything before he was scared off, so they claimed no crime had been committed. If you haven't already insisted on filing police reports for each incident I'd start there, and then maybe go to your CM.

An older friend of mine has a file with the fbi because she pooped there after hours after a protest.
