I'm in a walking cast and had wheelchair assist last week and while going through the metal detector, it went off. So SSSS put me in the special clear room so I can't get away so I could have additional screening. (I had gimped through the metal detector).

The female TSA agent came and told me I was selected for additional screening because the metal detector went off. I proceeded to point to my boot and say: there's a lot of METAL on this cast. So then I get the pat down and the WMD swipes...

While the agents were friendly and non-threatening, it just seems like a waste of everyone's time and resources to think: hey, the wand went off on the METAL of the boot and that's why the METAL detector went off.

I don't see how much harm I could have done in a foot cast and a wheelchair.
