Why?

I think if there are millions of people who can justify assassination for their country/ideology, they'll be able to justify planting child pornography too. They'll just look away from the pictures themselves, just like they've looked away from every single other atrocity committed in their name. It's not like they have to pull a trigger: they have to print out some paper, stick it an envelope without looking while repeating to themselves "I wasn't the one who took the pictures" (if they even get that far in their thought process), and go about their business framing someone. It's even easier if they work in tech because they probably don't even have to open the file. Just grab ten thousand binary blobs from the database and thats it. One will be enough! Then they'll go home to their children, look them in the eyes, and forget all about it.

Perhaps I'm just too cynical.
