There are any number of compelling reasons the US would want to have a good information relationship with other countries, from counter-terrorism and cyber-crime prevention, to simple tax identification. This information sharing is not only necessary to strengthen relations with foreign governments but to protect the country from threats, foreign and domestic. But how does the U.S. government share such personal information with foreign governments? John Kropf -- Corporate Privacy Executive for Northrop Grumman and former Deputy Chief Privacy Officer for the U.S. Department of Homeland Security -- and Neal Cohen -- Berkman Fellow and part of the Privacy & Security practice group at Perkins Coie LLP -- discuss information sharing matters covered by their new book "Guide to U.S. Government Practice on Global Sharing of Personal Information, Second Edition," as well as developments which have occurred over the past year, including the Transatlantic Trade and Investment Partnership (TTIP) negotiations and the renegotiation of the Safe Harbor Framework.
