The number of terrorists who have been caught because they were controlled by a police officer "because they ran a traffic light" (yeah, sure) is wild.

In the EU at some point after every single terrorist attack the terrorists' names were known because they had left their passports in a car they left at the scene. (yeah, sure again).

The really amazing thing is that they don't know the name of the terrorists right away: because the terrorists don't have the passport on themselves apparently. No: they all leave them in the last car they used.

Probably that, by now, terrorists see past terror attacks and think: "Oh, I'm supposed to have my passport with me, but then leave in the last vehicle I'll use before killing people".
