We have the base security enforcing 15 MPH speed limits (on roads that would be 25 or 30 MPH off base). A friend recently got a ticket for not making a complete stop at a stop sign. The security policeman said you will be ticketed if the car doesn't actually settle backwards slightly before proceeding.
I only mention this because this happens to people who actually work on base, and yet somehow, with such stringent application of the rules, these muzzies actually got on base.
The MPs are definitely “men with a mission.”
