Passenger name record

The idea of setting up a PNR file (passenger name record) for people who move around by planes in Europe is a Loch Ness monster story that comes to light momentarily whenever there's a search for terrorists, then it disappears once again.

At present, both Manuel Valls and Bernard Cazeneuve have been strongly advocating this PNR project.

Do terrorists of the kind that concerns us today actually move around in Europe on commercial airliners? That would surprise me. I'm reminded of the joke about a fellow, having lost his keys, who's searching for them at the foot of a lamp post. Somebody asks him: "Are you sure you lost them at this place?" The fellow shakes his head. "No, I don't think I lost them here... but the light from the lamp post makes it easier to search for them in this area."
