You seem to be forgetting that this is FR, where rights are those things that only some people have.
I’m sure that if a FReeper had pulled his gun on an attacking dog, shooting it dead, the incident would have been hailed as a great armed-citizen self-defense move. But the knee-jerkers don’t want to even wait to find out if the dead man was given warning, etc., before passing judgement against him.
I always imagine these guys as being Chinese, and try to evaluate the evidence in terms of who is trying to save face ~ which seems to be a characteristic Chinese (in general) and American cops and gang members have in common (the need to develop the polite lie that absolves one of blame).
