We are familiar with terrorism. But indiscriminate, cross-border, religiously motivated terrorism is new.

Indiscriminate attacks on civilians ought, under all circumstances, to be illegal in war as in peacetime.

In the fight against terrorism, national agencies keep full control over their police forces, security and intelligence agencies and judicial authorities.

Police forces collect information to be used in a public court to get people convicted. Security services gather information that does not necessarily lead to people being prosecuted and in many cases needs to remain confidential.

In situations of military conflict, civil strife, lawlessness, bad governance, and human rights violations, terrorists find it easier to hide, train and prepare their attacks.

If you exchange information internationally, you must strengthen data protection. Those are two sides of the same coin.
