I will just restate again that certainly we've heard anecdotal information from law enforcement that...my friend is correct: the misinterpretation of the legislation--because there is some room for interpretation--has hindered law enforcement.
Our position is that even if 99% of the ISPs cooperate and 1% don't, it's not good enough. If there's one child out there who's left behind, left to be abused, left to have their images used when we could be stopping it or trying to stop it, then we need to do more.
