A lib I work with who has good politics about Palestine (shocking given his politics on basically everything else) had this to say in regards to the treatment of professors and student protesters.
All I could think was "have you been living in a cave?"
This guy actually believes the hype about America; Never mind the BLM protesters who were also arrested and given unacceptable prison sentences, never mind the national guard getting called on protesters, never mind cops killing protesters from time to time, now this is isn't America.
It's been America for a long time, I've no idea how he hasn't noticed to be honest.
Show them the footage of the police driving around in unmarked vans shooting pepper balls at protestors during BLM - or just people outside in the area of the protestors. Or the people just watching from the porch of their own home: https://youtu.be/LozQg0oX-Gw
