1. Yeah, much like military.
2. While we are a large department, Presidential Details are staffed by one unit where we know all know each other. So, not easy.
3. Never watched it.
Yep. I always cringe when, in the movies, someone "dresses up" like a regular worker and slips right past people who have allegedly worked in a group for years. When I worked in the jail we knew each other by face and by voice on the radio. It didn't take long. In the military all our hair may have been short but you knew everyone in your platoon.
Just want to make the story go their way so, hey, let's throw out reality.
Regards and Happy New Year,
