Yeah, the cop is much more likely to unload one or more high-capacity magazines than the bad guy is. But you're wrong in this way: shot-for-shot the cop is no more likely to hit a target than is a bad guy(BG). Difference is the cop won't quit shooting until he's out of ammo (likely multiple 20-round magazines) b/c he's required to stay at the scene, whereas the BG will (sensibly) leave ASAP.
