Just one day after the attacks of September 11, 2001, the German minister of the interior, Otto Schily (SPD), demanded a new security concept. Immediately the existing security laws and precautions were placed under special scrutiny in search for any sorts of deficiencies. The results of these reviews were two legislative initiatives, termed “security packages” or “anti-terror packages,” which changed or altered numerous existing statutes. The new security laws contain a number of infringements into fundamental civil rights and liberties. The legislative process thus had to raise the issue of the relationship between security and civil liberties and weigh the balance between the protection of individual rights and collective security. This, however, does not constitute a new challenge for the German legislature. The collision of security interests with individual civil liberties has caused a legal problem in Germany for some time. September 11 might constitute a political watershed, but in the context of civil liberties in Germany, this date does not represent an important mark. The current measures have to be understood within the context of an at least thirty-year-long period of continuous weighing between security and freedom.
