Well we saw that many law enforcement are sympathetic to one group but see the other group as an opportunity to "lay down the law"...even you can admit the 2 groups were treated very differently....right? Eh, nevermind.....it's funny that you assume every protester this summer was "the left" but considering almost no Trumpist righty would even be slightly annoyed about a cop murdering a black man slowly on video....you could be right. Besides all the instigators of course
FiveThirtyEight had a good article on this a couple of weeks ago.
Data collected by researchers at ASU show that, worldwide, authorities are twice as likely to respond with force to left-wing protests than they are to right-wing protests.
