Last November, Robert Glenn was a 5th District D.C. cop on a robbery task force. Members of the group stopped a van at 2nd and V Streets NW, and Glenn noticed that one of the passengers seemed to have some marijuana in his lap. He told the man, 20-year-old James Fawole, to get out. Fawole initially resisted. After a struggle, he gave in and stood at the car door. Then Glenn punched him in the face.

It was the cop, not the suspect, who stood in a D.C. courtroom one year later.

According to prosecutors, another officer on the scene suggested that Glenn apologize. Fawole demanded his name and badge number, but Glenn gave him false information. Court papers say that the six-year veteran also made false statements to the U.S. Attorney and the FBI. So he faced potential charges for obstruction of justice, making false statements to a federal official, and violating federal civil-rights laws.

But Glenn pled guilty on Tuesday only to simple assault, which could result in a 180-day jail term and a $1,000 fine. Glenn won’t have to worry about jail yet; his plea agreement said that the government wouldn’t seek to hold him before his Feb. 14 sentencing.

Instead of hard time, the government is content with collecting his badge. Under the plea agreement, Glenn has seven days to hand the city his resignation.

Glenn’s attorney declined to comment on the case.
