I was out of town on business yesterday, and couldn't comment, so reading today to catch up. I personally feel that the right verdict was reached for Chauvin. He messed up, and whether he intended to or not, Floyd died as a result of his actions. He absolutely made it the work of other cops, all around the Country, more difficult and dangerous with his actions last year.
However, regarding your statement above, in return to Archy. You say a legal system that habitually screws up verdicts in cases like this. That word means regularly, repeatedly, customarily, to become a habit.
That is your view, and you are welcome to it. But, perhaps, in whatever other cases you refer to, the verdict isn't one you like but is not "screwed up" or incorrect. Rodney King is the one blinding "screw up" that I can think of. That was 30 years ago.
