And I agree that "it is unethical to knowingly keep evidence of an accident", and I wouldn't do it.
A lot of you don't seem to understand what an insane thing the machinery of the legal system is. Once it starts running, it'll squash anybody in its path, unless they happen to know the meaning of "is" and the secret handshakes of the Club.
On that we are in full agreement. Someone once said that there are so many laws on the books that, if the government wanted to, they could successfully prosecute every last man, woman, and child for SOMETHING. As conscientious as I try to be, I probably violate a few dozen laws/regulations every day.
And chillingly the Feds said "there is no particular threshold." I.e. if you pick up a piece of junk after the ridiculously short amnesty and later realize it might be a piece of shuttle and are so stupid as to turn it in to your local police in person... wham there could come the juggernaut. I hope the courts slap the feds and hard, early in this process.
