hmm... let me see:
How about the fourth amendment (I keep forgetting - the constitution only matters when it is convenient)
Or how about the National Security Act of 1947.
Sorry - you are right - these are just minor inconveniences - let's make sure we give up our liberties in the hope that it provides security.
The 4th Amendment states: "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
Since when has AlQaida bothered with getting a warrant to mess with the people in this country?
BTW, you are "secure" against only UNREASONABLE searches, et al.
So, what's UNREASONABLE about chasing the enemy to ground in wartime?
I'd be more than happy to participate, gratis, and without even working as a government agent.
Now, regarding "liberties" that are given up, that hasn't happened. I do hope AlQaida and their running dog lackeys have given up their "liberties" and their lives as we defend ourselves against their attacks.
