I was watching Hasan being at the protests to get a sense of what is actually going on and a European left a comment on his video that succinctly put the US police into perspective.

As a European I don't get how the police is just shooting rubber bullets instantly, why do they not have riot shields and water throwers and such, it seems so uncivilised.

And that pretty much sums up the cops in the US. They're just uncivilized. Their idea of "deescalation" is escalation until you're too incapacitated to fight back.
