I’ve read it, and it’s really good.
These days, law enforcement at all levels — from the local cop shop to obscure federal agencies — uses snitches to trap ordinary people. Snitches tell lies that send their friends to jail. Paid agents provocateurs talk or trick otherwise harmless people into committing crimes. In many places, Snitch culture has virtually replaced real investigation of real crimes.
Don’t think you’re exempt if you’re a “law-abiding citizen.” The most trusting, naive, innocent people often make the easiest targets for these weaselly, lying, opportunistic vermin. Snitches specialize in targeting the vulnerable.
