Floyd, 46, died Monday night after being pinned to the ground while handcuffed with an officer’s knee on his neck. Video of the incident showed Floyd pleading that he could not breathe while the officer remained kneeling on his neck.

Magic Johnson spoke out as well, saying “George Floyd was clearly murdered by a Minneapolis police officer. How many times do we have to see black men killed on national television? This has been going on for entirely too long. We need to start seeing black people as human beings and not animals on the street.”

Four officers that were involved in the incident were fired Tuesday night. Minneapolis Mayor Jacob Frey called the incident “wrong on every level” and stated it “does not reflect the values that Chief Arradondo has worked tirelessly to instill. It does not represent the training we’ve invested in or the measures we’ve taken to ensure accountability.”
