Edward Snowden’s leaks exposed fundamental differences in the ways Americans and Europeans approach the issues of privacy and intelligence gathering. Featuring commentary from leading commentators, scholars and practitioners from both sides of the Atlantic, the book documents and explains these differences, summarized in these terms: Europeans should ‘grow up’ and Americans should ‘obey the law’. The book starts with a collection of chapters acknowledging that Snowden’s revelations require us to rethink prevailing theories concerning privacy and intelligence gathering, explaining the differences and uncertainty regarding those aspects. An impressive range of experts reflect on the law and policy of the NSA-Affair, documenting its fundamentally transnational dimension, which is the real location of the transatlantic dialogue on privacy and intelligence gathering. The conclusive chapters explain the dramatic transatlantic differences that emerged from the NSA-Affair with a collection of comparative cultural commentary.
