Here is a guy who declined the scan and then tested positive for explosives during the routine pat down.
He has no identification showing a fixed residence.
He has no identification showing his work place.
He can't provide a phone number they can call to verify his work.
The two people he says he's meeting can't be reached by phone either.
These are all legitimate red flags for security to follow up on.
I don't see what the problem is here. This is actually the TSA doing what they should be doing.
