Post Racial Society Exhibit B

What do you call a black police officer who is not in uniform? Take a guess!

At least one cop has been disciplined for ordering the NYPD's highest-ranking uniformed black officer out of his auto while the three-star chief was off-duty and parked in Queens, the Daily News has learned.

"How you can not know or recognize a chief in a department SUV with ID around his neck, I don't know," a police source said.

Chief Douglas Zeigler, 60, head of the Community Affairs Bureau, was in his NYPD-issued vehicle near a fire hydrant when two plainclothes cops approached on May 2, sources said.

One officer walked up on each side of the SUV at 57th Ave. and Xenia St. in Corona about 7 p.m. and told the driver to roll down the heavily tinted windows, sources said.

What happened next is in dispute.

In his briefing to Police Commissioner Raymond Kelly, Zeigler said the two cops, who are white, had no legitimate reason to approach his SUV, ranking sources said.

After they ordered him to get out, one officer did not believe the NYPD identification Zeigler gave him.
