The criminals are split up and offered the following option: • If A and B both snitch, they each serve 2 years • If A snitches and B stays quiet, A goes free and B serves 3 years • If B snitches and A stays quiet, B goes free and A serves 3 years • If both remain silent both will serve 1 year for reckless endangerment
