What you do in a training scenario and what you do when it actually happens are two different things.

You’re absolutely right, and that may be the case. However, it must be admitted that is is much more rare to not follow your training than to carry out what you’ve trained for when you train for a specific scenario. Plus, this wasn’t even a split second thing. The fact that they’re at the door talking to the dude for a significant period of time gave them a lot of time to do the whole ‘one gun, one taser’ cop thing.
