I totally understand. Can't necessarily support the private army, fiefdom warlord position, though. As for shooting out the window at somebody attempting to rob or rape on your property, that would probably fly, especially if the wife was shooting video of the attempt. Nothing in TN law says you can't shoot without leaving the relative security of concealment and (somewhat) cover of your structural walls of your castle, under the castle doctrine.
ps. Never ever shoot "at" somebody. Either shoot
them after considering the situation, being aware of the backfield or don't shoot. Just my person opinion, for what it's worth.
