A Sacramento cop attempted to swipe the phone of an activist, but backed off when he realized another activist was recording him.

As a result, we get two videos; a 3-second video showing the assault and a longer video showing him backing off while accusing the first activist of blocking traffic.

But the video shows the activist was standing on a sidewalk.

However, the video also shows he was holding up a sign stating “End Police Brutality,” so perhaps that caused the cop to strike out.

The incident took place Saturday during the Occupy Sacramento demonstration, just one of about 40 protests that are taking place around the country stemming from the Occupy Wall Street protest.
