14/85 wouldn’t allow them to requalify at the firing range, but then paper targets don’t shoot back. I very much doubt there were any warning shots or “suppression fire.” Police are trained to “shoot center of mass” until the threat is no longer a threat. Sounds like that’s what happened here.
Try running down the block then shooting at a torso at 40 feet and see what your kill shot ratio is,
then consider the fact the target at the range wasnt shooting back.
