Cases like the David Miranda detention really bring the political worms out of the woodwork. There's always a reserve army of right-wingers ready and willing to defend the indefensible.
It's annoying that Louise Mensch is still considered a legitimate voice in British politics but she's an excellent weathervane for the younger, more PR savvy right-wingers in the world. Like their elders, their capacity for entirely unabashed hypocrisy is amazing.
They're the kind of people who think that the government can't be trusted to run schools and hospitals but can be trusted to have unlimited powers of detention, powers to gag the press, to wage illegal wars and to abduct, torture and assassinate people willy-nilly. That stuff's all fine but trust them to collect and spend taxes on public services - hang on now!!! That's tyranny!!!!
