Something written from the FBI, like a receipt that the FBI has received the evidence and it is therefore of no consequence if the files are deleted. Something that will keep him out of jail if by chance another unrelated law enforcement agency happened to be investigating and became upset or suspicious because evidence was disappearing.

Ok, fair enough. I assumed that that was a somewhat trimmed-down version of the actual discussion, for the sake of telling their story briefly.

I didn't imagine that the FBI would literally have a 30-second conversation with someone who claimed to have child porn in their possession, with no actual follow-up or action steps discussed.

But I can see how that would seem problematic if you did take it literally.
