Seven months after the Edward Snowden leaks about National Security Agency spying started becoming public, President Barack Obama is now saying some changes in programs may have to be made.

A Blue Ribbon panel appointed by the president, Review Group on Intelligence and Communication Technologies, recently published a 309 page report.

One of the conclusions in that report were that the NSA program of vacuuming information about phone calls and other electronic transmissions within, into and out of the U.S. was, from all available evidence, worthless as a tool to fight terrorism.
