Not necessarily sam, it is in his neck*
After the alarm/beeper goes off they pull you to the side to swipe you down with those hand-held metal detectors. He won't have any problems until they go near his neck, then they'llbe like: "this dudes got a bomb/gun in his neck" lol nah
Unless a tiny gun is hanging in your throat..
But obviously you need to remove it eventually, it will cause nothing but neck/back/ and headache problems, but the longer it stays there the more your body adapts
