It's a very good question that I had not turned my mind to before you asked it. I think that based on my experience these Internet child exploitation investigations are complicated. We do a lot of training of police officers and it's important that people who are using these tools be appropriately trained.
I can't speak to what the Canada Revenue Agency does, as that's not my field of expertise. My expectation is that any law enforcement officer utilizing this should be appropriately designated and have appropriate training.
My experience is with police officers and I believe that's the core. If it extends beyond to people in other fields who don't have the training, there's a greater risk of inadvertent misuse. Then I would agree with you that it's a risk.
My experience is limited to police officers, though, so I can't comment on the extent to which those other people might have the expertise needed.
