NSA whistleblower Bill Binney and ACLU of Massachusetts Executive Director Carol Rose spoke to a packed crowd at MIT on November 19, 2012. The conversation focused mainly on the military's warrantless wiretapping program and the FISA Amendments Act, but covered a host of topics related to technology, liberty, privacy and security.

Perhaps unsurprisingly given the venue, the question and answer session was pretty fascinating in its own right.

Take a listen.
