Some cops could use a hug. Others could use a Huggy Bear. Like Starsky and Hutch's trusty tattletale, reliable informants provide us with a worm's eye view of their sordid social circles, a heads up on threats to officer safety, and the groundwork for search warrants. They hang in circles we wouldn't want to enter. There is no question that the access they have and the intelligence they acquire is often invaluable to law enforcement.
