In the era of intense government surveillance and secret court orders, a murky multimillion-dollar market has emerged. Paid for by U.S. tax dollars, but with little public scrutiny, surveillance fees charged in secret by technology and phone companies can vary wildly. AT&T, for example, imposes a $325 activation fee" for each wiretap and $10 a day to maintain it. Smaller carriers Cricket and U.S. Cellular charge only about $250 per wiretap. But snoop on a Verizon customer? That costs the government $775 for the first month and $500 each month after that. Regardless of price, the surveillance business is growing. The U.S. government long has enjoyed access to phone networks and high-speed Internet traffic under the U.S. Communications Assistance for Law Enforcement Act to catch suspected criminals and terrorists. More recently, the FBI has pushed technology companies like Google and Skype to guarantee access to real-time communications on their services. As the number of law enforcement requests for data grew and carriers upgraded their technology, the cost of accommodating government surveillance requests increased. AT&T, for example, said it devotes roughly 100 employees to review each request and hand over data. Likewise, Verizon said its team of 70 employees works around the clock, seven days a week to handle the quarter-million requests it gets each year.
