Liberty is the very center of freedom. Liberty is having the freedom of choice, sans any say so from any authority. Any regualtion that is remotely resrtictive denies liberty.
Privacy is the idea that noone will interject into actions you desire to be private. As an example eavesdropping on someones phone call would be a violation of that, becuz they are only speaking to that person on the phone.
Everytime privacy is stolen from us, we risk losing freedom then. Every small infringement could potentially be disastrous to what we understand to be freedom.
As Americans we beilve we have a right to privacy, and that our government will allow it. In fact, the Bill of Rights expresses this. Lets hope in the future that will be remembered.
