Well trained enough to accidentally shoot suspects. Not to pick on PA State Troopers, but how exactly does your firearm “accidentally” go off into a suspect’s shoulder? More than anything, I’m picking nits with the author of the article; that sort of thing should really be labeled a negligent discharge, and not an accidental discharge.
I don’t know exactly what types of firearms the PA State Troopers carry; however if it’s a Beretta or a similar type of weapon with a decocking mechanism, I can see how this might have occurred. Since I know that Sebastian is from PA, maybe he can shed some light on the PA State troopies issue sidearms.
