I'd encourage people not to contact any law enforcement entity of any kind if they don't have a really solid understanding of the situation. Consider this story from a few weeks ago: https://news.ycombinator.com/item?id=33626670 where someone called the cops because they were concerned that they saw a child walking alone, and the mother ended up going to jail. That wasn't the intention of the person who called the police; but once you invite law enforcement into someone else's life, you have no idea what they will do and you have no power to recall them. 'pessimizer relayed a similar experience yesterday: https://news.ycombinator.com/item?id=33836312
I honestly encourage everyone to consider whether letting it go is the best thing to do in any given situation. Someone might've stolen money? Contacting law enforcement probably won't get it back. An organization is dissolved? We can form it again, with a structure that ensures a higher bus number. These are things we can control, and where we can predict the outcome.
