If you are an NRA member and receive any of their magazines, I hope you read "The Armed Citizen", a monthly feature that describes the legal use of firearms.
And these happen out "in the country", in "nice neighborhoods", etc.
The majority of the incidents are within the home, and none are announced. Whether you are awake or asleep, day or night, if someone suddenly busts in your door or window, you are at a disadvantage.
If you have to go find your gun you are at a significant disadvantage.
