“The federal government has significantly expanded undercover operations in recent years, with officers from at least 40 agencies posing as business people, welfare recipients, political protesters and even doctors or ministers to ferret out wrongdoing, records and interviews show,” The New York Times reports.
“Some agency officials say such operations give them a powerful new tool to gather evidence in ways that standard law enforcement methods do not offer, leading to more prosecutions. But the broadened scope of undercover work, which can target specific individuals or categories of possible suspects, also raises concerns about civil liberties abuses and entrapment of unwitting targets. It has also resulted in hidden problems, with money gone missing, investigations compromised and agents sometimes left largely on their own for months. …
Some of the expanded undercover operations have resulted from heightened concern about domestic terrorism since the Sept. 11, 2001, attacks.
But many operations are not linked to terrorism. Instead, they reflect a more aggressive approach to growing criminal activities like identity theft, online solicitation and human trafficking, or a push from Congress to crack down on more traditional crimes.
At convenience stores, for example, undercover agents, sometimes using actual minors as decoys, look for illegal alcohol and cigarette sales, records show. At the Education Department, undercover agents of the Office of Inspector General infiltrate federally funded education programs looking for financial fraud. …
It is impossible to tell how effective the government’s operations are or evaluate whether the benefits outweigh the costs, since little information about them is publicly disclosed. Most federal agencies declined to discuss the number of undercover agents they employed or the types of investigations they handled. The numbers are considered confidential and are not listed in public budget documents, and even Justice Department officials say they are uncertain how many agents work undercover.
But current and former law enforcement officials said the number of federal agents doing such work appeared to total well into the thousands, with many agencies beefing up their ranks in recent years, or starting new undercover units.”
