The Constitution is designed the way it is because our founding fathers feared government even more than they feared criminals. They even included a way to change it with amendments. Unfortunately, our government thinks like you do. They legislate measures that are directly forbidden by the Bill of Rights without amending. Why are people like you so afraid to just edit or rescind the fourth amendment? Or declare martial law? Those are the only two ways that you can grant government the kind of power the "patriot" act gives it now. And when a democrat administration starts abusing the power regularly, I guarantee you will be here screaming your head off over it.
Unfortunately for you, the majority of citizens think like I do and are sick of the liberal and libertarian mantras that support criminals.
