There is a television commercial out right now and it has a couple in bed and they hear a noise in the house at night, the guy gets up to investigate, without a weapon, he sees someone breaking the door down, runs back up to the bedroom, shuts and locks the door.
This is a great example of how cowardly people are becoming. If I had got up to investigate a noise, i would have grabbed my 18.5" pump ( with pistol grips) shot gun, and used it instead of running to my bedroom. Could i have been killed or injured in the meantime, yes, but then again both my wife and myself could have been killed by allowing the intruder to enter unopposed.
And, this of course, is a ploy by the media to show people what they "should do".
