Do we literally choose between freedom and security?
There are many types of freedom, and some do get restricted in the name of security, but the bigger choice is privacy versus security. To maintain a secure environment there must be monitoring of activities. I live in Las Vegas, and cameras are everywhere. Telephone monitoring, satellites, recordings, background checks, and more.
There is a balance point.
That seemed to be the consensus amongst those who wanted to reorient the way America was to see the terrorist threats after 911.
