A San Francisco police officer twice struck the camera of a man who was filming a demonstration against the Bay Area Rapid Transit system on Monday.

The videographer is Erik Verduzco, a journalist student, who was standing on a street corner video recording officers handing out water bottles to other officers.

Officer A. Mora took offense to this simple gesture, so he struck Verduzco’s camera.

When Verduzco zoomed in to get Mora’s badge number, the officer struck him again, but not before we could see his badge number is 2349.

A second officer even had to step in to restraint Mora.

The officers all ended up walking away.

The demonstration stems from BART police shooting in July as well as the fact that BART police shut down cell phone service in one of the earlier protests.
