One thing I think the present uprising indicates is how far leftward US culture has moved in the past few decades. When the Rodney King/LA riots happened, they were mostly limited to the LA area and a few other places. This time the uprising was nationwide and spread to small towns. Also, when George H. W. Bush sent out federal troops to quell the uprising in 1992, it wasn’t even controversial. This time around, the Deep State vetoed Trump’s interest in doing the same.
