I think people of today, think differently than they did 5years ago. People's perceptions and thought processes evolve, and there's no denying that.
Let me put it this way, as it relates to the Constitution. Yes, we have more to fear from isolated terrorist attacks. Yes, we have more to fear from islamic radicals intent on murdering anyone that doesn't agree to their version of Islam. That's evolved over the last 2 decades, punctuated by the events of 911
However, the Constitution is what sets this country apart, from nearly the rest of the globe. It's a blueprint, literally a rulebook. Yet within the rulebook is a means to modify the rules, if evolved will wishes it. When you play poker, does 1 of those nights 2 pair beat a straight flush? Of course not, that would be changing the rules. Now, if everyone gets together and decides to change the rules as a group, fine. But intil then, the 4th amendment still protects this country's citizens from unreasonable search and seizures.
And though some may "feel safer' with the added level of groping & sexual harrasment at the hands of the TSA, or pornagraphic images taken and to be oodled by all its members, minus a presumption that every passenger is a suspected terrorist, it is wholly unreasonable for the TSA to be conducting their current level of searches at the mandate of the Federal Government
