I think the most dangerous people to many of us are our neighbors. People can be unbelievably petty, jealous and vindictive. If a national red flag law is passed and publicized, I think a lot of false reports will be used to settle petty disagreements over what color you painted your fence or I don't like that you park your work truck in your driveway.
I'm trying to be the nice guy with the neighbors, but some of them simply seem angry at the world.
