It's a personal value judgment whether you think the camel's nose is a problem. The facts remain, however, since once the police get this list, they're going to ask for more search queries from the people on the list, because it's easier to create a defendant that way.
And then just add those people to a list of people who should be watched closely at transportation centers.
And then maybe make them wear a little orange circle on their jackets so they are easier to identify.
And then maybe put them all in a concentrated containment area so the rest of us were safe from all the would-be terrorists?
Or maybe at that point filter it down to just the orange-circles who happen to be from germany.
