Baltimore welcomes a new discussion series that promises ‘conversation with a purpose.' It's called Great Talk. Co-founder Diane Davison gives us an overview, and we meet former National Security Agency executive and whistleblower, Thomas Drake. He will headline the panel for the inaugural event next week, titled: ‘Cyber Wars, the Secrets, the Spies’. A few years into his tenure at the NSA, Drake brought concerns about wasteful spending and questionable surveillance to his superiors, ... but was thwarted, then charged with espionage ... His life hasn't been the same.
