After the astounding story of the tragic death of the LEO trainee recently, in which 2 of the 4 basic rules of gun safety were blatantly violated (apparently repeatedly and under the SOP/training policy), I have to ask, do LEOs in training environments (or otherwise) consider themselves exempt from the 4 rules, due to their training? I'm not asking to be smart-alek; I'm truly interested to know whether they focus on and hammer the 4 rules (they were the 3 rules in the old days), or not? Because it's just amazing to me that the police training scenario in question in the other thread could have so blatently violated the fundamental rules of safety (repeatedly). Would that cavalier attitude be the exception or the rule in police training scenarios across the US?
