These HOA types often seem to get a bit overzealous these days, and in many cases like to pretend that they are the neighborhood police!
A coworker of mine (a fellow police officer) told me of an incident that happened to him a few years ago within our jurisdiction, where he lives. Apparently my friend was taking his trash out in the evening before collection day, at which point he was confronted by a lady who identified herself as an HOA representative. She told him that his trash wasn't allowed to be placed at the curb until a couple of hours later, or something along those lines. He disagreed with her understanding of the issue, and told her that he would be leaving his trash by the curb. At this point the lady apparently produced a badge, and stated that she was a "sheriff", and demanded that he comply with her request.
