ABSTRACT
Guarantees of security and justice are the core functions of any modern state and so-called state monopoly. The importance of effective cross-border information exchange had been raised on the European Union (EU) political level after the terrorist attack of September 11, 2001 in the United States and intensified after the attack of March 11, 2004 in Madrid. The European Commission proposed establishing EU Information Policy for law enforcement based on the improvement of information exchange and to introduce the concept of intelligence-led law enforcement at EU level. The principle of availability became a cornerstone for police cooperation in a similar manner to the principle of mutual recognition, for judicial cooperation and "The general political and practical guideline for the exchange of law enforcement information in the EU". Legal acts regulating police cooperation refers to different terms: "information", "intelligence", and "personal data" or "intelligence".
