This New York Times article reports that Democratic leaders want to conduct increased oversight of counterterrorism programs, including wiretapping and data-mining programs. Senator Leahy made this opinion clear during a hearing yesterday questioning Robert S. Mueller III, director of the FBI. These investigatory plans are very encouraging. Mr. Leahy said he was troubled by recent reports about the Department of Homeland Security’s use of a scoring system to rate the risk that people coming across American borders might be terrorists or criminals. He said the program and broader government data-mining efforts could make it more difficult for innocent Americans to travel or to get a job — without giving them a chance to know why they were labeled a risk.
