15 years is only 2009. I don’t think we’ve had any major protests in that time frame, so yeah any brutality looks unhinged. All I can think of is Occupy and the DAPL protests, and those were smaller and slightly less brutalized. Get back to me when you learn about Blair Mountain.
Of course that’s not to take away the seriousness of police brutalizing protestors in the first place. It would be so trivially easy to just stop supporting genocide.
