I got up the other day after a long night, not fearing anything being wrong, just the usual morning. Still a little sleepy I turned to my PC just to find this in my face: "Germany on high alert due to 'plot'"
I panicked. Immediately I called my local police station to report these weird looking Middle Easterns who moved in next door. They don't speak German, they don't look German, they just look like a big bomb waiting to explode to me. After what seemed to me the longest half hour of my life, a black van pulled in the driveway, men rushing to my neighbor's door with weapons drawn, kicking the door in. I hear screaming and loud noises. Five minutes later the men escorted these monsters out the door, into the van and tagged them with a yellow star. What a relief.

Oh no, wait. I think I got a little bit confused with history there. Anyhow.

So, I was relieved, lying back proudly in my chair thinking I did a fine service to my country when suddenly the men from the van rang my doorbell. They were probably going to thank me, or so I thought, so I opened the door just to suddenly have a gun in my face and get arrested. What for? The reason seems obvious enough, really. I'm a terrorist. Now that I think about it, it all makes sense. How could I, as a citizen of a democratic country, read articles by a terrorist network like Al Jazeera? What was I thinking? I must have been out of my mind. Of course the Stasi logged what I was doing on the Internet and acted appropriately.

OK, fine. While this might have been a work of fiction in some parts, just take a minute and think about what my point is.

Let me quote what the interior minister of Berlin, Ehrhart Körting, said:

"If we see something in our neighborhood, if suddenly three rather strange-looking people move in who try to keep out of sight and who only speak Arabic or another foreign language that we don't understand, then I think one should make sure the authorities know what is going on." - Ehrhart Körting (Spiegel article)

And with the findings of a "bomb" in Namibia that apparently was headed for Munich, Germany, I have reason to be scared, or do I?
Let's recap.
What appeared to be a "bomb" was found at the airport of Windhoek, Namibia. It was a suitcase which had:

"batteries that were attached with wires to a detonator and a ticking clock". - Bundeskriminalamt (BKA) statement

Later it turned out that this was just a "test". A testing device manufactured in the U.S. for usage at airports and other security areas, to see whether detectors and employees will detect the major threat this device eradiates. Have you seen the device? It's actually pretty funny:

It reads:

X-RAY TEST OBJECT NON-HAZARDOUS

and some info about the manufacturer (Larry Copello Inc.) below. On a funny but irrelevant side note, the wiring was apparently done by an 80-year old woman.

Question is, who planted this device? At the moment they're blaming it on a police officer in Namibia.
Whoever they're going to blame it on, let me see if I got this right:
You're telling me a device that appears to be a bomb was found at the airport of Windhoek, Namibia (which once was a German colony) and was supposed to head for Munich, Germany one day after Germany raised their "terrorist threat level" because they're fearing an attack. Really? They're still looking for the culprit?

The only real terrorist here is politics and that's about it.
