A few years ago when I was on vacation I discovered that the owner of a coffeeshop I liked was retired Secret Service. The place wasn't busy, so we sat around and talked. (Bush2 era). And he had so much sympathy for agents who were assigned to guard obnoxious people who endangered them, and so much anger about the endangering. (Rumsfeld, for one.) I have been thinking of him and his friends for a while lately.
