Even if he is convicted of a less than the top count or convicted of the top count, but the penalty isn't severe enough for the mob's taste, BLM will schedule riots. The only thing that BLM wants is vengeance for their hero George Floyd.
Well, first there is going to be a break between verdict and sentencing.
Second- get this - there's no BLM central command that schedules riots. Either people will be satisfied justice was done or they won't be.
When Jason "16 shots" Van Dyke was convicted in Chicago, there were demonstration, but no riots. Then a couple months later, on the coldest day of the year, they held a long-ass hearing on his sentencing before the judge gave him a mere 7 years (probably out in three) despite hearing a lot of stories from other people he abused.
Yes, people want JUSTICE for George Floyd. They also want reforms so this sort of thing doesn't happen again. These are not unreasonable requests.
