Why don't they care about the evidence in the George Floyd trial?

   I whole thing doesn't make sense too me. They found pills with Floyds saliva in the back on the police car. George Floyd was complaining how he couldn't breath before they pulled him out of his car. There where high levels of drugs in his system which the doctor who autopsied Floyd even agreed how the drugs played a part in his death. There is a video of Floyd saying how he ate to many drugs. In my opinion the only thing they can get Derek for is use of excessive force. They have yet to prove intent and to prove what killed him. I believe Derek Chauvin is not guilty of murder. And now because of Floyds death black criminals can pretty much get away with anything, and when a black criminal gets shot it automatically considered murder. I feel like the whole BLM movement and the Floyd family hate cops, and especially white cops which is why their demanding a conviction and threating to burn some more if he is not convicted. What the hell is wrong with these people?
