Promotions, or just having their superiors leave them alone. We have similar problems in France with quotas. Policemen are encouraged to arrest a certain number of people per year, or else. The problem here is that they are evaluated by the number of arrests (easy to assess), instead of the actual efficiency of their work (very difficult to assess accurately). This evaluation method is of course as disastrous as lines of codes are for programmers. As a result, 1% of the French population has been arrested at least once last year. And this number is increasing. Another example would be the number of American citizens that are on the Terrorist Watch List (I recall 4% [citation needed]). Official may get brownie points for putting one in, but never for putting one out. (Plus, there's might be an almost non-null chance that the guy might be, or know, a terrorist. Perhaps.)
