At the latest since 9/11, the EU took severe changes in their home affairs policy. New agreements and institutions were created to facilitate police networking (Europol, Frontex, CEPOL, new databases and their shared access).

Risks" should be minimized by taking more and more "proactive" measures and foresee possible "threats".
