The Security Trainers have enough to go over, do we really need them to cover lead exposure?  Unless the Officer is working at a Firing Range, he won't be exposed to enough lead in the course of his duties from discharging his firearm that it would be a worry.  If the officer IS firing his gun that often while on duty, then there are more important considerations.  Frankly, as an armed officer of 25 years the only times I've had to worry about lead exposure was when people were shooting at me.
