The names have been changed to protect the . . . . oh nevermind.
Hitch hiking back, a car with two guys stopped for me; I noticed that both were unshaven and pretty scrungy looking, and we were already up to speed when I noticed weapons all around the car.
Turns out they were state cops on the way to work; they stopped again - all bright and shiny and cleaned up in their patrol car about an hour later to assist me getting the VW primed (I'd run out of fuel and was parked on a hill making it difficult to get the gas pumping right).
...to protect the ignorant?
