Hefets is not a guy and this is not a quote from her (or at least, it doesn't seem like a quote). Or do you mean the author of the article? I can't imagine that, because there's not reason to think he was arrested, so why you bring up that "that guy should not be arrested but straight up jailed or deported" (wtf)?

And why would the sit-in being illegal matter over whether this is police brutality or not? In the video I see the police grabbing a woman's face for no apparent reason (and also the face of the guy in the background) and then wrestling her to the ground and I don't see why the police would need to do that just to get her out of there.

So you want to jail and deport people for the terrible crime of looking at that and having the perfectly reasonable interpretation that this is excessive use of force and police brutality and saying that??? Fucking hell.
