Almost 50 years ago, when I was a very young Lieutenant in the U.S. Army stationed at a large Army hospital out West I was assigned, as an additional duty, the role of Provost Marshal and command of our small (20 man) military police detachment. (For what it is worth, I was a Medical Service Corps officer with no training or experience in law enforcement, but the MP branch in Washington was so pressed for MP officers due to Vietnam requirements that they could not fill the slot at our hospital). The Commanding General called me in one day and asked if it were true that my MP's carried loaded weapons, even when they had to enter the hospital itself. When I told him that this was correct, he "suggested" that I consider having them remove the magazine from their 45acp auto and leave the gun unloaded in their holsters. Being a young and inexperienced officer I took his suggestion to be just that, a suggestion and not an order, and I never directed my MP's to unload their service weapons while on duty. I'm convinced that this General and probably others in the command never realized that their MP's were actually carrying loaded weapons, but I knew, and I wanted it that way.
