Even from the outside this is obviously true. They consider themselves the good guys by definition, because they see themselves as representing justice, as defined by the criminal code. A noble calling. Once you accept that, pure job performance (convictions) becomes an easy metric. The thought of ruining some individual's (or family's) life over recreational amounts of pot is either justified or compartmented away. Or like aaronsw...once the prosecutors are on it, there's no more question of proportion or actual justice, it's a matter of looking for the conviction. Edit: I want to amend this a bit. It is something of a noble calling. In a better world, the executive legal function could depend a lot more on legislative and judicial functions to produce a criminal code that served justice better, and just worry about prosecuting what they can according to the law. But in so many cases now, the law is an ass.
