It's like the episode of The Wire where Herc and Carver plant a remote microphone inside a tennis ball to listen in on some drug dealers and attribute their evidence to a non-existent confidential informant named 'Fuzzy Dunlop'. They need to invent a CI because they hadn't previously convinced a court of the need to surveil those persons and so they had nothing they could use in a trial. I'm not a lawyer so I can't say if the legal issues depicted were depicted accurately, but I recommend the show to anyone interested in the topic of surveillance for the purposes of law enforcement (as opposed to intelligence gathering) and how things can potentially go wrong despite their good intentions.
