That there plot thickens:

A chicken isn't a rodent. No, I got that FBI thing right from the site on the purple clicky that Bert posted.

Seriously, if the people on the spot don't know whether the engineer had a heart-attack or not, or whether he was on the train or not, or whether it's the conductor or the engineer--check that out--why should we think they will know the diff. between the FBI and the NTSB? I'd rather the Boy Scouts of America did it; they have adult leaders.

PS. Until the number of female railroad engineers reaches parity with the number of males, I will abstain from political correctness on the subject of deadman switches.
