What can happen when you snitch?

Lots can happen when you decide to become a confidential informant, i.e., a "snitch" for law enforcement. Sometimes snitching gives criminals protection to continue their crimes. Cops might steal the money you were supposed to be paid. Or, the cop might become your informant. Perhaps you'll help bust a ring of rogue baking-soda dealers. You might get the crap beat out of you. Maybe the DA will get you to snitch against your own lawyers. Or maybe you'll get a chance to testify against the Sheriff's son.
