This one shows plainclothed Basiji thugs (pro-government vigilantes) on motorcycles, often doubled-up (guess the regime can’t afford a bike for each one). If you pause the video at exactly 10 seconds in, you’ll see what looks like a couple of masked goons. In the past, the this has been a hallmark of the Hezbullah goons. They are often involved some of the most brutal attacks. I have witnessed several videos in which they are savagely attacking people with knives and batons.
