I don’t believe this story.
You are warned over and over not to enter with metal. How it WILL kill you, if you do. And he thinks “Ok it probably does not mean a metal handgun I have hidden”
You don’t go in one wearing clothes. Wear was hi hiding the gun? up his ass?
It will suck a metal object right through your skin.
What clothes was he wearing that the operator could not see a gun?
It was his mother getting the MRI, not him...............
