Colin Kaepernick has a message for the people protesting the death of George Floyd: It’s not only within their right to fight back; it’s absolutely necessary.

Floyd, a Black man, died after a white Minneapolis police officer Derek Chauvin held his knee on his neck while Floyd laid on the ground and said he couldn’t breathe.

Four officers arrived, and 17-year-old Darnella Frazier filmed Chauvin with his knee on Floyd’s neck.

All four officers were fired from the Minneapolis Police Department the following day.

People also marched to Chauvin’s house and were met by police in riot gear.
