If you think any of those three would support as you've described then you don't know any of them.
You clearly haven't been paying attention to what they have said in this thread.
George Floyd was a thug. He was a criminal who resisted arrest. He had drugs in his system. He was in possession of illegal narcotics and counterfeit cash. It may be that the reason he died is because he OD'd on fentanyl. But they support Floyd, the criminal, against the cops.
The recent police shooting in Wisconsin is a similar situation. The guy was a thug, a worthless criminal. He resisted arrest and assaulted officers. He was armed with a knife. When he attempted to enter his vehicle (to retrieve a gun, perhaps?) he was shot in the back as he deserved. But not according to our resident Democrats. To them, the Black criminals are the good guys, and the [White] cops are the bad guys. It would be ironic indeed if any of them ever had to call 911.
