I'll have to have a look at this one. Have seen several reviews of the incident. One thing that came out of this and a shooting in New York was the psych component of those involved in shooting a human.

1) is the unwillingness of a human to take the life of another. Affects the good guys way worse than the bad guys. Several reasons for this, I won't go into at the moment as I am posting on the internet not writing an essay.

2) the stress to shoot before been shot, also, results in most shots being wild. This side of things is being addressed more and more. Not sure how this will continue with a lot of new police, as they don't like being put under the kind of stress that attempts to emulate-to a small degree - real life stresses.

3) They shoot once a year and need to do way more than this to introduce muscle memory on the firing sequence, so they shoot with a steadier trigger pull instead of a jerk.

A lot was learned by the worldwide policing community from this incident, bad guys reactions and why they have the ability to absorb many shots. Most police that have military combat training have/develop these abilities.

Most police forces are not willing to spend the time and money to over come most of this. Some do have range time when any that are interested can turn up for practice and guidance. How many make use of this I have no idea but guess it would be minimal.
