Ok, I saw an episode of Brain Games regarding expert intuition of law enforcement personnel some time ago that came to mind recently regarding Officer Wilson.
Scientists have discovered a second type called expert intuition, which is the sort that comes from special training and experience. Studies of nurses in the 1980s, for example, revealed that those who had been in the profession for a long time tended to make better judgments and to do it more quickly. In a study published in the journal Science in 2011, researchers examined the brains of expert Japanese chess players and found that they utilized different regions of their brains while playing than amateurs did. In particular, they had more activity in the precuneus area of the parietal lobe, a region associated with visualizing images and episodic memory. When they needed to come up quickly with a move, activity surged in the caudate nucleus, where goal-directed behavior is rooted. The researchers believe that the experts intuitive skill resulted from a circuit that they had forged between the two regions from many years of training.

Here's part of the clip about LE expert intuition.

In essence, the episode says expert intuition allows LE to more quickly/accurately observe and act on information than laypeople, in determining a suspect as an example. Makes sense to me, and reinforces why laws allow for what the officer reasonably believes. Not only did the "for no reason" witnesses lack all the information Darren had at the moment he fired, but they also would not be as skilled at evaluating the level of risk or need as an officer.

PS There's more about LE intuition via google.
Meh. Can be turned right around in fairness. Could bolster the argument that OW recognized MB wasn't a threat. Additionally, what kind of training has OW received. Something tells me if he were tops of his class he wouldn't have been in Jennings and then passed over by the County to land in Ferguson.
