Redeemed Corrupt Officer. Dixon is a very racist incompetent cop, but one who respects his boss Willoughby deeply and who really did want to do good in his community.
Drinks often, even on the job. Ultimately, his worst moments come whenever he's intoxicated. Dixon is trying to administer justice as he understands it. He is ultimately well-intentioned but the results are always at best mixed.
He is probably a closeted gay. Loves listening to ABBA.
