As a wise man once said: "Pausing to consider constitutional implications means the terrorists win"
"The only way to defeat evil is precipitate and ill-considered action. A morally and legally coherent approach is the handmaiden of anarchy. Haste averts waste. You've never had it so good."
Come to think of it, it wasn't a wise man. Actually it was a politico twat looking for the next sound bite, amid the ongoing absence of parliamentary grown-ups.
