Um, whilst I agree that the powers that be are definitely anti-palestine, this is just a video of cops chasing a kid who happens to be holding a palestine flag.
Given that other people are also holding flags and not being chased, I'm guessing they're not chasing him just because he's holding the flag.
This is pretty disingenuous social media reporting.
Edit: The novaramedia link up in the thread does seem to show excessive police action against peaceful protest. I don't think the video shows this, but it could be related.
