Police Officer shooting

We had to watch this video on the first day of ROE/RUF training. In case the video is kind of blurry (it is from a dash cam), the officer stopped this individual, let him go back to his truck and retrieve a semi-automatic rifle from the cab. While the individual was loading the rifle right in front of him, the cop just yelled at him until the suspect began to engage. The police officer had been reprimanded, apparently, for being too heavy handed with subjects. At one point during the fight you can see the subject literally brushing off the hits from the handgun. Not a fun video to watch.
