Zacs- that this is not a choice of one v the other. Floyd is dead, gone.
The question now, is what you think of Chauvin's behaviour- and if he is also the kind of person you would trust. You don't need to choose between them, it's pointless.
You can have independent views on each. And much as I'm not sure Floyd was a great citizen (although, honestly would prefer him as a next door neighbour), the current question is- is Chauvin a decent, reliable individual. From what I have seen so far, I would have to say no.
