Customs can open letters and packages to or from foreign destinations. Why should international telephone calls automatically be exempted from these rules? What do you say in your international phone calls that you're so worried about? I know that no one would want want to listen in on mine, and I wouldn't care if they did.

As for the habeas corpus comment - the question here is where the line should be drawn between constitutional rights of ordinary criminals and enemy combatants. No on thinks that soldiers on a battlefield should be bound by Miranda, rules of evidence and civil procedure, etc... But where do you draw the line?

Instead of fighting about this, maybe people should pay more attention to important freedoms, like the freedom to travel; to own and enjoy property (buy and sell it freely, develop it, etc); to freely practice religion; to speak freely, etc.
