you know, you're right :) just to add, it's not only the trigger that can put into movement by the magnetic forces, or some secure-hinge, it also can be heat induced by magnetic fields / induction / in the bullet itself. I stay with my view, though. When the gun were not brought in, it could not go off and, thus, no fatality. Its the gun & bullet that killed its possessor and not the MRT or the process of "bringing it in". The same would not happen with a printed, non-magnetic gun (if we put aside the bullet's ferromagnetism, if any..). So two guns - both brought in - one goes off - which one killed?? Like you said, horse hockey. I could follow the argument "its not guns killing human, its the bullets" :)
