I can’t think of a method of accidentally igniting a primer in a bag... If UPS is able to handle 5000 in a box,hundreds in a bag should not be an issue. The accidental ignition story stinks like a search for drugs that came up with primers.

I have to agree with you.
Anyone familiar with Primers and their packaging would Tape the individual Boxes so they could not slide open and then either tape the 1000 count box as well or at least wrap up the 100 count boxes in a sock or something like that.
No way could they accidentally go off unless they were loose in the suitcase and even then I have my doubts. They would have to come out of the suitcase and be crushed in some manner.
