This guy was old enough to have been a contemporary of Hitler’s. Having these kind of violent homocidal tendencies and acting them out at 88 years old? And how many people that age are shot - wasn’t it twice? - and survive to get to a hospital? Most people that age are up to gardening at best as far as physical activity. I just find it all very weird and have to wonder what we’re not hearing about this guy.
I'd have to rate pulling a trigger as less strenuous work than gardening.
