Motion sensitive lights all around, certain ones connected to lights and alarm in house, dogs that love to bark and bite, and if that dosn't stop them, gaurded at bare minimum 6 nights a week with Smith an Wesson or Remmington 870, they can try to guess which nite someone "might not" be home.
Thieves are a scurge in our country, and if more people put rounds of munition into any thieves ever seen, then maybe others thieves would figure, "it just ain't worth it". GD bleeding hearts who dont understand that a well trained civilian gun population is the only true freedom from terrorism. If just one of the first few kids to get shot at in Columbine, had a gun to shoot back with and had been taught from an early age how and when to use a firearm, it wouldn't have been the travisty that all the bleeding heart gun control freaks caused. It woulda been a minor shooting incident with just the bad guys dead. Ain't to say that innocents can't or won't get hurt, but it sure as hell would happen a helluva alot less.
