Minneapolis police lieutenant calls length of time knee was on George Floyd's neck uncalled for

Lt. Richard Zimmerman with the Minneapolis Police Department Homicide Unit testified Thursday that the length of time former officer Derek Chauvin's knee was on George Floyd's neck was "just uncalled for" and "totally unnecessary." He said he saw no reason why the officers would have felt they were in danger once Floyd was handcuffed, and they would have had to feel that way to justify using deadly force against him.
