>I imagine that a team looking like low wage municipal workers driving old municipal vehicles
Seen that happen when I was in DC once.
Bunch of people on the sidewalk across the street (WH side) waiting to see a foreign dignitary exit the Blair House.
Limos lined up waiting. Traffic light changes to red. Guy in a produce truck waiting at the light blocks the view . Light turns green, Driver stalls the truck. Driver fucks around a little, and when he starts rolling limos are gone.
Also, all those bums sleeping on the Lafayette Park benches (or panhandling) , aren't bums.
