Once handcuffed with his hands behind his back, he's not much of a threat. Once handcuffed with his hands behind his back a person shouldn't be placed face down as that restricts their breathing even without three men on top of them including one kneeling on his neck. If a person is cuffed with their hands behind their back and they are not on their own feet, then they're to be placed either in a seated position or laying on their side so as not to further restrict their breathing. What happened in this instance (?) & why?My opinion....Floyd was a piece of shit. That said, no one deserves to die that way. Once subdued, the knee should have came off the neck. The officer overstepped his authority.
