I've had the displeasure of meeting crooked cops before, and 'law enforcement agents' with no respect for the law, and I think for the most part the cops need to mind their own business.
But I also had neighbors who ran a puppy mill for a dog fighting ring, a neighbor who thought it was funny to set a can of cat food and a bowl of antifreeze at the edge of his property, and yet another neighbor who let his dog starve to death. (Thankfully I'm now a far distance from THAT neighborhood).
