It's a case of misplaced loyalties, union/associations, and PC culture.  Remember, most fit people don't let themselves feel the same hate we do. The PC culture causes this. They experience the terrible consequences of having fat people around them, but purposely don't think about it being the fat person's fault, or tell themselves that fat people can't help being fat, so it's wrong to get mad at them for being so shitty. Combine that with the strong feelings of camaraderie among member of law enforcement, and now you have a bunch of people who won't stand for fat being a cause to fire someone. The union/associations/order/whatever is based on those first feelings. Now the union won't let obesity be a cause for firing, so it goes from just the administration not wanting to fire an oreogre, but they now can't fire the oreogre for being so fucking gross.
