I don't disagree. We catch child pornographers all the time and they are on the bleeding edge of encryption. There's no practical benefit to banning encryption. The .gov just doesn't feel like going through the effort and would rather enjoy, say, the ancillary benefits to being able to read all of our messages forever.

But yes, the mere knowledge that pictures of you being abused on the internet is extraordinarily difficult to deal with. Maybe not the best direction to go in when arguing.
