Class Struggle

In The Black Dahlia James Ellroy's character "Bucky", an ex-boxer turned police detective, gives me a good idea for a profession/class connection in my noir mmo.

It seems Bucky came to the attention of the police force because he'd been a prize fighter and done pretty well, well enough to get noticed, anyway.

So I'm thinking there could be 2 paths into the police class:
1) You take some performance test (starting at lvl whatever) to enter the academy, then progress normally doing low level police missions ("quests" seems like the wrong word), until you gain faction and promotions, etc.
OR
2) You gain faction via a Boxing PvP (Player verses Player) arena. You have to perform at a certain level, like x amount of wins, or x global ranking before you are approached by a police rep who wants you to join the force at an elevated level.
