Tragically, many law enforcement officers are injured and killed every year during training exercises. This roll call program depicts the death of a State Trooper shot to death by another trooper who thought his weapon was not loaded. 

For many officers, dealing with rape victims can be one of their most traumatic experiences. It's also a very painful experience, obviously, for the rape victim. 

Defensive Tactics Expert Sgt. Mike Muxo of the St. Louis Metropolitan PD explains and shows several of the tactics bad guys utilize to "get over on the cops" in this two-part roll call special.  

Another tragedy that can teach officers crucial lessons and safety procedures. A  jailer transporting a prisoner from one facility to another is shot to death when the subject seizes the female deputy's service weapon from her and opens fire.
