You were a rabbit and since you were little you have always wanted to be an officer although others made fun of it since your species was low-ranking but you had hopes...
After turning 25, you moved to Zootopia where all types of animals lived together and in peace, hoping to become an officer but they only gave you the position of traffic officer.
You were on the street giving tickets until you saw a fox... it looked suspicious until you found out that that fox was selling food without a permit, undeclared transport between neighborhoods and false advertising. After this fox finished his scam work, he simply left, as if nothing had happened, you immediately followed him and told him that you had him under arrest, he just looked at you in a sarcastic manner.
"Oh, really? Why?" Craig said sarcastically.
