Seems that someone must be blamed and punished.
This reminds me of something that happened to a friend of mine years ago. He was driving in the winter and hit a patch of what is called black ice. He slid off the road and hit another car that had hit that same patch of black ice and slid off the road seconds before him. When the police came, he was ticketed for causing the collision.
He challenged it in court. When the ticketing officer was put on the stand, the judge asked him for the rationale for charging my friend. He said that the department's philosophy is that if there is an accident, then someone MUST be at fault, and that person MUST be charged with causing the accident. No exceptions! Since there were only two people there, he had to choose from those two options, and the obvious choice was the guy whose car slid into the first guy. The judge said that was ridiculous, and he dismissed the case.
I think a lot of people in positions in law enforcement have a similar notion--in any kind of incident or accident,
someone must be at fault, and that someone
must be charged.
I have seen that attitude in threads on ScubaBoard over the years, even in cases where the victim clearly suffered a heart attack during the dive. Well, what happened during the dive that caused that heart attack? If the dive buddy didn't do something to cause the diver to panic and have that attack, then the fault must lie with the instructor and agency that did not supply the quality of instruction that would have prevented the (unseen) panic that caused the attack. (After all, all heart attacks are the result of panic.)
