this is why tapping a spent shotgun shell above a person’s bag to go to the airport is such a terrible joke. it gets detected and they get in trouble. i heard it also works with peanut butter because of the high nitrogen content.

however black powder will no be detected because it has no organic nitrogen.

some csi stuff about their hands and gunshot residue of fine metal particles could also be an answer but is not likely
