Agree that our great white fathers in government don't subscribe to an armed response. But, guns should be your last line of defense. All the advice offered to dissuade burglars/home invaders from targeting you remain valid. These include, lights, cutting back shrubs, alarm system with panic buttons, a dog, locked doors, are all valid and should be done. When all else fails, the home invaders will flee once you shoot the first one. It ain't Hollywood. They won't want a shoot-out.
Here's where you can get into deep doo-doo. Don't give chase, putting rounds in their backs as they flee down the driveway. Call 911, ask for medical assistance for the guy you shot. And don't execute him if he's still alive. You'll be charged with murder.
