Did you know that the EU is working on a "Handbook on Terrorist Organisations"?
It could be that this thing already exists although the search term on Google doesn't produce any results. But in the summary of discussions of the last meeting of the EU Council Terrorism Working Party (agenda item 6) there is a short hint to the "update and distribution" of this handbook.
Oh, and in the same document we learn that representatives of Marriott Hotels International Ltd and of the Rezidor Hotel Group were invited to speak about terrorist threats and the difficulties to combine hotel work and vigilance during the working party meeting.
I feel more protected now.
