And that ain't always so easy to do. Their first two shots to the back of their own heads are hard enough to pull off, but when they try to shoot that third shot there, their head is no longer there, so, at that point, they're just shooting at the air...
I know its not easy to shoot themselves in the back of the head 3 or 4 times, but I am sure they will figure out a way to do it. Whats even more difficult, is for them to shoot themselves in the back of the head, 14 times, but the authorities will find a way, and laugh at us, when we question it.
