I am firmly-albeit-reluctantly OK with this, if the alternative is widespread surveillance of what should logically be private correspondence/communication among private citizens.

I value the privacy of the hundreds of millions of the citizen population over a slight increase in the conviction rate of the tens to hundreds of thousands predators.
