A pedicab driver was tased by a U.S. Park Police officer Friday outside the Air and Space Museum, but the police account and the witness accounts don’t match up. Police say the pedicab driver assaulted the officer. Witnesses claim an assault never happened and that excessive force was used.

According to police, officers told driver Charles Guillon to get out of the crosswalk, but he refused, so they threatened him with a ticket. Police say Guillon then assaulted the officer, and that’s when he was tased.

One witness says the police account is erroneous.

“I didn’t see anything that looked remotely like an assault or battery on the police officer,” witness Tyler Clark told WJLA.

In June, WAMU reported on the growing tensions between U.S. Park Police and pedicab operators as the bicyle taxis proliferate on the National Mall and Capitol Hill. Police claimed they weren’t cracking down on the operators, but allegations of harsh treatment continued to surface.

WTOP reported this morning that D.C. Mayor Vince Gray said on a former Ask the Mayor program that D.C. should and will regulate pedicabs.

“The question is, which agency is the most appropriate to regulate them, is it [the D.C. Department of Transportation], is it the [Department of Consumer and Regulatory Affairs] or is it some other agency,” Gray said.

Pedicabs are currently treated like bicycles, subjecting operators to the same rules as cyclists.

“They’re like bicycles, but they’re not bicycles. They’re like automobiles, but they’re not automobiles,” Gray said.

Gray told WTOP that the D.C. Department of Transportation has written up draft pedicab regulations.
