People already showed that they will swallow anything as long as it's attached to "protect from the terrorists" label. Protect the children is an even more powerful extension. Few people ever really have to worry about terrorists but kids, that's a different story.

My logical assumption is that all terrorists and pedophiles will concentrate in the areas where they have legal exceptions from being monitored by multiple different parties at any given time. Legislators and the like. To play one of their cards, why would people who love to say "innocent people have nothing to hide" have something to hide?
