You ever notice how these shootings NEVER, EVER take place at firing ranges?
Apparently not that rare.
There have been a few murder/suicides at ranges lately. The latest I recall was in Utah.
I realize the story is from across the pond, however, back here in the US of A we had a nutjob take out her own son last year at a firing range.
Nobody saw it coming, she shot, then when the son stepped up to shoot, she shot him in the back of the head.
I'll see if I can find a link.
