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.

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.
