You may be radically underestimating the degree to which the Internet has made it possible for people who abuse children to share content. In some cases, these crimes truly couldn't be perpetrated without the anonymity of the Internet, and the existence of these clustered communities of pedophiles encourages further abuse/exploitation.

I love the Internet, and my career is in security. But we as a security/privacy/technology community truly need to look hard in the mirror about how we are allowing and perpetuating lifetime harms to children and women.

Terrorism exceptions, like San Bernardino, don't ring with as much impact as the CEP argument.
