Months before the shooting death of Justine Damond and the international headlines that followed, prosecutors say there was a routine traffic stop that shows former Minneapolis police officer Mohamed Noor had a history of “unnecessarily escalating force.”KARE 11 obtained police dashcam video – never seen publicly before – of the May 18, 2017 traffic stop.Prosecutors want to show the video to the jury when Noor is scheduled to go on trial in April. He is accused of second degree murder in the death of Justine Damond Ruszczyk, an Australian-American woman who was shot and killed after police responded to her 911 call for help.In court filings, prosecutors argue the video of the traffic stop shows Noor pointing his gun “at a man’s head” when the driver was pulled over for a minor traffic offense. It is one of three “prior acts” they want to introduce “to prove the common scheme or plan of unnecessarily escalating force, his intent and state of mind at the time of the crime, and that he committed the crime without justifiable accident or mistake.”Noor’s defense attorneys are fighting to keep the video out of court. They argue the prosecution’s description of the incident is “grossly misleading.” The defense says Noor was justified in pulling his gun and he had it in “'low carry’ pointing down between himself and the driver.”
