OK, once again I'm not getting it. At CDG. I went thru the metal detector. It beeped. I had already taken off all metal things, including my belt, that I was wearing. The guy wanded me. It went off at hip level on my left side. I reached down there and realized it was a security wallet I was using that hung inside my jeans. It had a clip that was metal. I pulled it out and threw it on the conveyor. The guy wanded again, all clear, we both laugh, and I proceed.

So now I'm wondering: You step into the scanner. The spook sees an "anomaly" in your pocket area. You pull out the wallet. Oh, that's all it is. You proceed?

What am I missing here? In searching for anomalies, they are trying to PREVENT ones that are totally innocent?
