Introduction

The challenges presented by terrorism to our governments in the past decade have led to fundamental changes in many things. The way we travel and the way we bank have, for instance, changed perceivably. Some avoid travelling to the USA—the country formerly known as “the leader of the free world”—out of a desire to avoid the need for a passport featuring biometric information or “being treated as a criminal” surrendering fingerprints at the point of entry. The more data protection aware amongst us may have changed the way we use the internet and other forms of communication technology or simply accepted the feeling that we can be watched at all times. Less obviously, a new security architecture has emerged around us and for Europeans, the EU looms large within it.
