Time that you can use to re-evaluate the situation, unless you fail so epicly at multitasking that you have to watch yourself insert your fresh magazine and concentrate fully on this task lest you fuck it up somehow.
This coming from a person who at one point, after a lot of practice, could disassemble and reassemble an M-1 Carbine rifle in 59 seconds blindfolded(Yeah, it was stupid but my buddy and I were having a bigger-penis contest).
I propose that department marksmanship and gun handling training is substandard.
Edit: It takes about 6 seconds to empty a 17 round magazine. Quick math means about 3 rounds a second. It would take about that time to reload the weapon and re-acquire the target.
We don't know motivation, or this particular officer's level of training or his psyche evaluations. But from the evidence presented, he indicates either a desire to shoot until he runs out of rounds or substandard training/ability to maintain composure under pressure. Any one of these three things is a trait I do not want in Law Enforcement personnel.
