I'm certainly no expert on this [or anything else, except maybe for Top 40 from the 1975-1990 era
]. However, for what it's worth, I have been wearing concealable body armor at work for 24 years. I always wear the trauma plate. In fact, my most recent department issue vest came with the usual soft trauma plate, and I wear both that one and also an older steel trauma plate of the same size behind it. It seems to me that more protection is a good thing, and it would also seem that if I do take a bullet there, I should [theoretically] not feel it as much. Besides...if a suspect should try punching me in the chest, he's going to himself a LOT more than he'll hurt me!
