Rule 6: Undercover work

6a. AVOID UNDERCOVER WORK

6b. An undercover assignment is the most difficult type of detective work as it often forces the detective to go against his nature and pretend to be something he isn't, i.e. a normal person.

6c. If the criminal under investigation suspects that the undercover operative is not 'a stand-up guy' and is possibly a 'ratfink stool pigeon', then statistically the undercover operative has a mere 14% of survival.
