“Use of informants is ethically questionable. The DEA ends up paying money to dubious characters, albeit toward busting bigger drug loads and bigger criminals. In theory, agents cannot pay informants actively involved in criminal activities. In practice, agents try not to know what their informants are up to. As they admit, “these guys are not choirboys.” Agents are also worried the informant could be a double agent who is feeding info to the cartel. Or a triple agent. Daniel discovered you have to push into an informant’s mind to make sure he is playing straight.”
