Undercover operations can be risky for the agents who spend a lot of time with the criminals. They may become unable to draw a line between impersonating and becoming lawbreakers. After successful undercover assignments these agents suffer from depression, anxiety, lethargy and lack of motivation, even personality changes. Another risk is that the respect for and trust in the administration of justice may diminish, especially if government knowingly bypasses normal restraints and uses disreputable methods, such as deception or videotapes, to gather evidence.
