Developing policies for cops using robots with lethal force

This week we discuss the issue of police officers using robots with lethal force in emergency situations. After an initial 8-3 vote approving such a measure, San Francisco's board of supervisors reversed course this week and temporarily banned its police officers from using robots with lethal force. To break this all down, we're joined by Paul Scharre, Vice President and Director of Studies at the Center for a New American Security. ​Paul previously worked in the Office of the Secretary of Defense where he played a leading role in establishing policies around unmanned and autonomous systems and emerging weapons technologies.
