"Was Floyd's death justified" is a wrong question.

It implies: that his death has been proven, beyond any shadow of a doubt, that he was "killed"by law enforcement. And then asks was it okay for law enforcement to kill him.

There are no such conclusions. And your question is based on these false pretenses

Instead: there is a conclusion of medically based analysis of the body postmortem.

To ignore these findings is inappropriate.

You can ask: was the officers actions the significant contributing factor that killed George Floyd?

They are currently reviewing this as a matter before the court.
