Postal worker: I don't have to answer to Chicago cops

The Chicago Sun-Times reports:

A Chicago mailman was arrested after police said they saw him speeding though the Austin neighborhood on the West Side in a U.S. Postal Service minivan Thursday afternoon, as well as blowing a stop sign, driving without a seat belt, using an alley as a through street and wearing headphones while driving.

When the police caught up to Julius Campbell, they asked for his driver's license and his postal ID. But they said Campbell, 42, who works out of the Cragin post office at 5100 W. Grand, told them, "I don't have to show you anything," saying he wasn't bound by the jurisdiction of the police, only by postal inspectors.
