"History teaches us that grave threats to liberty often come in times of urgency, when constitutional rights seem too extravagant to endure."
-Justice Thurgood Marshall
Justice Marshall was right. Times of urgency are when tyrants come out of the woodwork to exploit tragedy. They salivate, and descend upon freedom like a pack of rabid dogs.* Necessity is, as William Pitt said, the argument of tyrants.
*I won't say how we deal with rabid dogs because, oh my god, that would be violent rhetoric on par with the words of our founders.
