The owner took out a huge homeowner's insurance policy on Santa days prior to the shooting.
Remember- This is bigger than all of us.
My advice- quit asking questions while we are ahead. Never mind there also appeared to be no exit wound in the video, something I'd expect to see if there was a firearm powerful enough to shoot through not just one, but - two layers of chinese quality santa nylon.
As I've investigated plenty of Santa inflatable killings from back when I was on the force. I know what I'm talking about!!!!!
This really does have the makings of a good youtube video. Recreate the scene in a controlled environment, buy several santa's and dispatch them with several calibers of real guns. .22, 9mm, 308, shotgun, blackpowder. Cordite in santa's butt.
