You Have Just Been Put on Administrative Leave for Screaming

You have just been put on administrative leave for screaming at and hitting a teen with a nightstick who was loitering and skateboarding in a public area after he disobeyed your order to cease and desist. Until you see the video of yourself on YouTube, secretly recorded by a third party, you didn't realize how angry you had become after being disrespected and disobeyed by the teen. You have no explanation for your behavior except that you were doing your job. You were placed on administrative leave because:

A) you are a "meat eater."
B) you used excessive force.
C) of extralegal factors.
D) of peer factors.
