OAKLAND, CALIFORNIA–At the “First Friday” Street festival, an African American man openly urinated on a Oakland Police Department vehicle in front of several witnesses, including Breitbart News lead and investigative reporter Lee Stranahan.

The unidentified man then walked away laughing, flipped a middle finger at the empty police car, and yelled “f*** the police!”

The urinater did not wish to be interviewed on camera.
