Chloe T. asks: Can police officers or FBI agents commit crimes while undercover? And any criminal operation could quickly weed out any such undercover agents simply by asking them to break a law and seeing what happened next. On that note, undercover agents can commit more major crimes, including even bribing politicians, so long as prior approval to do so is obtained. In response to the controversy, the British government introduced sweeping legislation severely limiting the ability of undercover officers to commit crimes and form relationships with those they were investigating. So to sum up, undercover agents in most regions of the world can absolutely commit crimes while undercover, though the extent and severity of the crimes they are allowed to commit varies depending on who or what they are investigating.
