Years ago as a cop reporter I covered a shotgun suicide. A large man sat at the kitchen table with the gun between his legs and the barrel against his throat aiming vertically up thorough his head towards the back. The blast separated the front part of his head but the jaw stayed in tact so his head flopped inside out then down onto his chest held there by the jaw. This is some 20 years later and the view is still quite vivid.
i remember seeing a video from a thermal imaging camera on an apache helicopter taking out insugerents with a 20mm a while back as well... thermal imaging is cool... i thought about getting a scope like that until i saw the price though
