You have the right to protect yourself and family ofcourse, but verbal threats alone are not enough to use force. I suggest finding local attorney who is experienced with laws regarding self-defense, defense of others, defense of property.
If cops don't do anything, go to the DAs office. The Cooke county DAs office in Gainesville can be pretty accessible and reasonable.
