He was a special volunteer in the AV Room and ran the projector when he was in high school. He had his lunch money regularly confiscated and his bicycle seat tossed in the dumpster by "the cool people". After a youth spent listening to the monikers "Doofus" and, "Shit For Brains", of course he'd grow up wanting to change his paradigm and possibly seek revenge on the "Cool People".
He'd search for any possible way to gain power over others and what could be better than a uniform, a gun, and codification that would protect him anytime he got overzealous or out of control.
This job was FUN man! He got to use guns and yell at people and make them "get on the floor" where he could knee them in the back, or break stuff and, hit them with stuff.
Whadda great job. Of course he wouldn't want to have to simply knock on the door. What FUN would that be...
Wha? .....hey....who stole my country?
