And had he "reacted to a noise" by trying to draw his service weapon, his partner would have all the time in the world to say, "What the hell are you doing?" especially since it's been reported that Noor was being evaluated due to questionable behavior on duty in the past.
Especially when wearing a retention holster like most cops prefer, like a SERPA holster. Thus the questions arise: Why was the gun unholstered? Why the finger on the trigger? If this wasn't intentional then it was criminally negligent.
Other reports say he had his weapon out and sitting in his lap as they drove up.
I read that Noor's partner has a year on the job, and that Noor has only 21 months, and in those months has three complaints lodged against him. One of the three complaints is sealed, another has resulted in a law suit. Why in God's name is he paired with an even less senior officer? The rookie could have possibly been reluctant to question the more senior officer's actions. Bad decision making on whoever made those assignments. And, I'm wondering if the complaint that's sealed is by a civilian, or from someone within the department that he harassed or abused.
