I think they wasted that much money in missed shots. Screwballs have been watching too many James Bond movies where everybody but the hero is a horrible shot.
You're missing an important component here. In the movies if the range is close, between cars, for instance, that are only a few feet apart, or across a room with the shooters hiding behind furniture, no one, not even the hero, can hit anything except in the last several seconds of the fire fight, the bad guys are spraying lead out of full auto firearms shooting up the cars or rooms(which ever applies)and the good guys are armed with semi-auto handguns and missing most of their shots, finally the hero shoots a perp, one shot from his handgun while the perps and other cops couldn't hit an elephant.
However, if they are outside and the bad guy is getting away and probably 100 yards down the street the hero can then hit him right between the eyes with a hastily aimed shot from his trusty 9MM.
The idea on the close scenes is to make a firefight last a long time to add excitement to the movie, never mind reality,who needs that? While on the long shot if the hero didn't hit him the perp would escape making the hero look stupid.
