If the manslaughter charge is correct, every cop that has had a druggie OD on them also is guilty of manslaughter.

lol, you left out the most important part, the cop had his knee on the Floyd's back and neck for over 8 minutes, that's what killed Floyd. Floyd did not die from an overdose.

[The guy did not die from a drug overdose]https://www.usatoday.com/story/news/factcheck/2021/04/16/fact-check-fentanyl-george-floyd-not-enough-to-cause-death/7239448002/).

While Floyd's toxicology report did reveal fentanyl present, expert witnesses at his murder trial have stated there was not enough to be considered fatal or impact his breathing and oxygen levels. Floyd died due to lack of oxygen from the force of Chauvin's knee on his neck.

The fact that the jury was overwhelmingly black...

You're lying.

o·ver·whelm·ing·ly | to a very great degree or with a great majority.

Among the 12 jurors and three alternates selected for the panel are three Black men, one Black woman and two jurors who identify as multiracial. If none of the three alternates — all of them white — is needed in the deliberation room, 50% of the panel that will vote on Chauvin's fate will be Black or multiracial.

Three black jurors and three jurors who identify as multiracial which could be white/asian, hispanic/middle eastern. So four of the 12 jurors are black, gee, that does not sound like an overwhelmingly black jury to me. Unless you're one of those people who believe one black juror is one too many.
