A Virginia driver saw flashing police lights in his mirror, but nothing was what it seemed. A teenager was impersonating an officer using blue lights. Unfortunately, the fake cop had chosen to pull over a real off-duty cop. The real cop suspected the fake cop, so he didn't stop. Instead the off-duty cop called the on-duty police, and the real officers pulled over the fake officer who was trying to pull over the real one.
