I read this and think of all of those episodes of Law and Order (SVU) where they confiscate the computers/video cassettes of @#%^philes and gleefully rummage through their stash of illegal images for evidence.
How easy would it be to pin this sort of scandal onto someone when they are involved in the creation of software that filters said content?
Way back in the day, I read an article about people hired to test filtering software. This was back in the 90's I think where "Net Nanny" style software was all the rage. Anyway, it was apparently soul-crushing work to spend eight hours a day looking at the worst the internet had to offer and the job had tremendous turn-over. Something like a matter of months. I'm sure those people had all sorts of illegal crap on their hard drives.
