President Bush is determined to spy on us without a court order. Let's get something straight; neither I nor any other liberal I know of has any serious objection to government eavesdropping in the legitimate pursuit of criminal activity, including potential terror attacks.
Here's the problem. Bush first said that warrants were obtained for all wiretapping; that was false. Now he says that we're at war and he doesn't need a warrant. But why won't he explain his reasons to an appropriate court and get a warrant? How are we to know that he's not spying simply because he has a "gut feeling"? Or for political reasons or even for personal enrichment? Should I trust him? Should anybody? The constitution says that we don't have to; he must satisfy a court that there is probable cause to believe that the person being wire-tapped might be doing something wrong.
I don't trust the government that much - regardless of who the President is - that's why the constitution says what it says.
If a President has that kind of authority over us then the nation the founders created is dead and we are merely feudal vassals. It makes little difference to the serf whether he's enslaved by a domestic tyrant or a foreign one, the revolt will be the same.
