UFC superstar Jon Jones is FURIOUS over the killing of George Floyd -- saying the police officer used a move called a "blood choke" ... and it's worse than torture.
"Anyone who has practiced the very basics of jujitsu recognizes a [blood choke] when they see this," Jones said.
"That was as clear as day murder, torture."
FYI, a blood choke is a stranglehold in which key arteries and jugular veins are constricted, cutting off blood flow to the brain ... as opposed to an air choke, which restricts breathing.
Jones -- who's been a top mixed martial artist for decades -- didn't stop there.
