What is truly odd to me is that every comment I read at several sites seems to absolutely believe that this story is true.

Basically, the bloggers and the commenters all seem to being doing exactly what the FBI supposedly did. Get some info. It fits with mindset. Act accordingly.

First, all the stories that I see are merely reporting what another newspaper (which I certainly can't translate) supposedly said. This is bit of a red flag.

The traveler was arrested? What charge? I can believe someone is detained, but arrested?

Email was received and acted upon quickly. Hmmm. That certainly matches my interaction with the US government.

I understand the Europe has pretty strict confidentiality laws, but there is not one single name mentioned in any of these articles.

Further, these are some pretty explicit quotes from a man who supposedly denied any involvement and now seemingly been charged with crime.

I'm sorry, but until there is a tad more information about this story, I'm going to assume that it is hoax.

Now if after the son-in-law arrived and he went to the library and checked out certain books...
