The article claims it is from 2001.
Claims the gun was cocked and locked and a series 80 to boot.
I've been in MRIs quite a few times. I did not need to take off my watch, or remove the partial bridge from my mouth. The clip board the tech was useing has a steel clip, and there were quite a few steel things in the room and none were drawn into the machine. So it seems odd to me that a holstered gun would fly across the room and fire.
