It seems to me like Noor shot Diamond in a split second. I don’t see how this would’ve given him time to consider her race (or gender or state of armament or footwear choice). Many people, when, say, a friend jumps out from behind something and makes a loud noise in an attempt to startle them, will react with a punch or something of the sort before really analyzing or understanding the situation. It seems to me that’s what Noor did. Obviously that’s horrible police work, and maybe even murder. But racially motivated? Doesn’t seem like it to me. In fact, what he wrote in the report aside (what was he going to say? She startled me so I shot her without thinking?), I would wager that if he’d given himself literally 3/4 of a second to figure out what was happening, he wouldn’t have shot her.
Chauvin, on the other hand, knelt on the guy’s neck for eight minutes, and for over two minutes after he was unresponsive.
