Nicely done.
There are some thing to be learned from this:
Bad Guys:
A: Either tie your shoes before the crime (even though it is soooo cool to slop around in untied shoes) or, do like your momma told ya, and always wear clean socks so she will not be ashamed of you when she has to go to the hospital to look at your shot up self.
B: If you are the first one in the door, that means you are the dumbest one, cause that means you will the LAST one out the door when the shooting starts and you can get shot in the ass.
C: Hang on to your gun, if through some miracle you manage to crawl under a rock somewhere, you don't want to leave fingerprints behind.
For the rest of us:
Notice that this guy did a lot of shooting and only hit one of the perps. Standing around down at the range shooting three stationary targets center mass is not the real world. These three were all moving very fast. What is important is that he started firing and got them all moving in the opposite direction. I am NOT criticizing him one bit, he kept his cover between himself and the guys with the guns and got the job done. The bottom line is that a bad guy got shot, no one else got hurt, and that is what counts. Any "coulda, shoulda, woulda" is mere speculation, it didn't go down that way.
I get the feeling we could have handed this guy a full cup of coffee afterwards and he would not have slopped any of it over the rim after the shooting.
