The first week of former police officer Derek Chauvin’s murder trial wrapped up Friday with testimony from the longest-serving officer in the Minneapolis Police Department, who said Chauvin violated police policy when he kneeled on George Floyd’s neck for nine-and-a-half minutes last May as Floyd repeatedly gasped “I can’t breathe.” This is Lieutenant Richard Zimmerman responding to questions from the prosecution.

Matthew Frank: “What is your view of that use of force during that time period?”

Lt. Richard Zimmerman: “Totally unnecessary.”

Matthew Frank: “What do you mean?”

Lt. Richard Zimmerman: “Well, first of all, pulling him down to the ground, face down, and putting your knee on a neck for that amount of time, is just uncalled for.”

More police testimony is expected this week, including Minneapolis Police Chief Arradondo, who in June said Floyd’s death was murder and “not due to a lack of training.”
