It seems Seattle wasn't the only place that turned violent during yesterday's May Day protests. A video uploaded to YouTube purporting to be of a May Day march in Los Angeles shows a protester walking up behind what appears to be a female officer and slamming her head with a drum. That sends the officer stumbling forward, and before she can regain her composure, the assailant runs off.

Here's how it happened in real time:

The LA Times reports that a female officer was struck in the head with a skateboard and taken to the hospital with non-life threatening injuries. It's unclear if this is the same incident and the attack weapons are simply confused, or if this is a separate attack.
