"Convicted" isn't the fear, post-9/11. The fear is getting put on a secret government watch list and being harassed for the rest of your life with no chance to ever clear your name, or even to be told why you're being screwed.
If we grant that such a list is wise to have, then sure, let's focus as much effort as possible on making sure that we don't put innocent people on those lists. But I'd much rather focus my efforts on not having the lists in the first place.
CEOP are the group that Google would report people to.
It's nothing at all. Plenty of innocent people are on those lists having done nothing.
That the pretext is terrorism is irrelevant.
"Terrorism" was just how they learned they could get away with it. Having established that, it's now any damn thing they want.
