Actually, for practical purposes, your question is the wrong one. A lot of people think the more ideologically pure argument is the one to make, but it's usually the one with the least impact and least likely to bring about your desired situation.
"Right" and "Wrong" are thrown out the window as soon as law enforcement makes the case that there is simply no time for the constitution. They're saving little tiny babies! but "OK, how many little tiny babies are you actually saving as opposed to blatant overreaches into the lives of private citizens" is the more effective point. The numbers will look bad, they can't help themselves once they get a whiff of some new power.
In this case, arguing for the _idea_ of liberty (incorrectly) labels you a pedant more concerned with red tape than being a hero.
