In Praise of the Rat Squad

Professions must police themselves in order to remain ethical and effective.

Professions know best what bad actions to look for.

But it is very hard to police your friends and colleagues.  It is easy for us to understand our own kind, and thus make excuses. It is painful to punish the bad, and to lose the those who are sometimes good, or used to be good. And it is embarrassing to the profession to air dirty laundry.

Nonetheless, no one hates a bad cop more than a good cop.
