I live at least 20 minutes from the nearest law enforcement and more than a mile from any neighbors. In our area, house break-ins involve up to 5 young hoodlums. What kind of mayhem could they do in 20 minutes to my wife and me? I have a lot better chance of surviving a break-in if I have a semi-automatic with a high capacity magazine. Just think of what happened to that farm family in the real-life killing on which IN COLD BLOOD was based.
When I go to be at night, all the doors are locked and there is a 9mm with a 17 round mag and a spare 17 round clip by my bed and so is my cell phone in case the bad guys would cut my land line. Am I paranoid? NO. Just like a Boy Scout - I am prepared.
