Wow... some interesting posts.
First off I'd like to comment on the NY Trigger. I currently have one in my Glock 19. Left over from my days with the department. There is nothing wrong with the NY Trigger IMO. I actually prefer it. IMO It allows the user to be a bit more aware of each pull. After training with the NY Trigger it's no different than a lighter trigger.
In my experience... shootings happen where they happen, when they happen, at the distance it happens. The police rarely get to choose any of these equasions. The only common thread in shootings is they happen very very fast. Officers, and armed civilians (I know the police are civilians too) are almost always are behind the curve reacting to the threat.
This shooting happened at an unusually long distance for an urban gunfight. This in my opinion is the major reason for high miss rate. Of course a practiced bull's eye shooter probably would have made the shot... but he may also have been killed by the perp. I didnt see anything in any artical about colateral damage to property or people. I choose to attribute this to the officers keeping their shots on target rather than using a cover by fire tactic. I'd love to know what the object the perp used for cover looked like.
The NYPD does not have a dedicated patrol rifle, but there are units within 15 minutes response time with rifles, shotguns, tear gas, and a bunch of other neat stuff. But even if the officers did have a rifle in the radio car they were in the fight with their hand guns. Like I say these things happen very very fast. They wouldnt have had the luxury of going back to the golf bag and choosing the .223 iron for this shot. You fight with what you have.
