The thing about weaponising child abuse to destroy democracy and privacy, is that no one can openly protest against it, because who the hell is against protecting children from abuse? Especially in Britain, where the spectre of child abuse happening basically in plain sight, is still fresh in anyone's mind (Savile & co.)
Child abuse is the trojan horse. Any resistance and fight for privacy has been on a ticking clock since legislators discovered they have the ultimate weapon to pass any form of anti-democratic regulation. Slap "it's for the children!" on top of it, and the masses will applaud and cheer for more spying and more profiling by the government.
