Luckily none of his victims were seriously injured or killed. Luckily this man had decorated his lawn in a timely manner. The moral of the story: Christmas saves lives.
On a serious note: how quickly and easily could this have gone horribly wrong? This is why I usually carry, even to family functions. My family usually scoffs, and this year I decided to leave my Sig at home when I went to a family dinner.
This story is a great reminder. Even if your family is sane and sober, you never know when the neighbor is going to barge in and start stabbing people. Keep your guns handy at all times...
...and when in a school zone, open carry a big plastic candy cane!
