I'm not criticizing the police offer that emptied maybe a 13 to 15 round magazine with one leg hit, because I have no idea how good of a shot I would be in that situation. But how common is that situation where an officer empties his firearm, and doesn't get any hits to stop the bad guy? Again it is a good thing the bad guy emptied his magazine, because he was able to come up behind both of the police officers without them knowing his position.
