I hope that you "well understand" that if these terrorists are not caught that you and we will suffer even more 9/11s. Waiting for the courts to issue a warrant will close the window for getting the information from their phone calls. The President took an oath to protect this country. He is doing just that. Instead of quibbling, you should be thanking him for living up to his oath.
I know that there are all kinds of threats out there -- and always have been, but that doesn't mean we get rid of the constitution. It would be neater, cleaner, and in a sense, safer, to let police go after all criminals without any constitutional restraint. That was true when the Constitution was written, too. But the Founders wanted this to be free country, not a police state.
If Hillary becomes president, I somehow suspect you won't be as enthusiastic for allowing government spying on people in the US without court permission. I certainly won't be enthusiastic about letting Hillary's goons do that -- but unlike you, I'm consistent. I don't want precedents created now - when our guys are in power - that could be used to undermine freedoms if Hillary gets in. That's what constitutionalism - and conservatism - are all about. A belief in the rule of law, no matter what party is in power. Marxism, on the other hand, believes - as some freepers seem to - that there should be no restraint on government, when "our guys" run the government.
So your point fails completely.
We do not invest any public official with the authority to simply do whatever they think is right. We are a government of laws, not of men. Those here who so slavishly worship the President and think that whatever he does must be okay need to pause and think about giving those same powers to a very different President.
It might be pretty to think that "The President took an oath to protect this country," but it's not factual or true.
Here's the oath the president took:
"I do solemnly swear (or affirm) that I will faithfully execute the office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States."
