Head shots fall DRT. They don't quit bodily functions for some time....
I'm not going to take the time OR the space now but I have several pix from the last few yrs.
Head, Neck, Hi shoulder (spine) shots. I have YET to see ONE move ANY part of their body.
I'm NOT saying it has not happened. I have seen too many Instant Dirt Naps......it doesn't take MUCH time.
