As I said, there's absolutely no reason to think anything like the thought experiment would happen in reality. What worries me is the possibility that it *could* because someone was careless - or worse yet, unaware. An IT nightmare scenario my network administrator and I have been trying to develop a defense against involves hackers planting such material on hard-drives at point of manufacture and wiping it so that only mere traces remain. I won't touch Bitcoin or any other cryptocurrency because of the way they work - the block-chain is more than likely replete with things best not touched by human hands.
I brought it up because the instructor of the forensics course I took in college (Jan 2010 semester) was simultaneously an academic and an RCMP officer (who had spent a significant portion of time in some of the more major sex crimes Canada had to deal with, as he worked the Bernardo case). He mentioned that due to the extreme nature of the material that those working the case had to examine, a few of the people involved later went on to help train US police units to enhance their ability to deal with similar cases.
It was a poor attempt at a "worst case" example and thought experiment that stuck my mind as I came across one of the papers I wrote on child pornography and cyber security for that course. I do apologize for not articulating the question and scenario better. Basically what I wanted to know was what's likely to happen if one is *mistakenly* thought to be carrying such material. I don't know why I used the parentheses.
Okay, I'll take the thought experiment at it's face. While I'm not CBSA, I've worked a few files with them, so I'll have a crack at it.
First - anytime I've ever handled CP administratively (ie to bring to the Crown or Court), it was on a stand-alone non re-writable finalized disc or drive (depending on the size of the collection) clearly labeled as containing child pornography. Attached to said disc is a chain of custody which lists everyone who had it in their possession and why.
There shouldn't be a need for anyone engaging in academic exercise to have the material on their phone or computer for
so many reasons. Now, let's say our academic exercised
extremely poor judgement and had the material on a digital device like a laptop or phone. If they say nothing about it, and it is found - you can bet that won't be solved at the local border level. An investigation will start, the devices will be seized, the "professor" will likely be arrested and off will his devices go for forensic analysis (with the appropriate warrant once obtained).
If the professor was up front, had clearly labeled what he had, he still may not be allowed into the country and may be arrested. The law is pretty clear that ordinary folks (even academics) are not to possess, access, distribute or create child pornography. When you throw a border into the mix, you can run into import/export offences as well. What the American law is - I don't know, but you can bet it will be a legal mess. As an investigator, I certainly wouldn't be satisfied with a phone call to the constabulary this guy was supposed to lecture at.
Thought experiments of this type are hard to muddle through due to the enormous amount of detail needed in order to properly contextualize what is going on. You would be better served by accessing a case law resource (such as canlii.org) and just start reading decisions.
