Here's my take on this and it's only my take or opinion.
If you look at this whole case, you know that all of the four officers will be convicted regardless of their tiny level of involvement.
Why?
Well, the courts wouldn't want another riot that will now take down that courthouse, too, and more losses to Target and other stores.
So, it's clear: the conviction is not due to actual guilt but just to halt the mob.
Floyd is a martyr now though, for having lost his fake $20.00 bill.
