Run, don't walk...
There has always been a tension between individual liberty and governmental power. National security issues are a natural fault line, given the difficulty of protecting the nation while simultaneously upholding the values of freedom and liberty. And politicians, bless their hearts, always try to find ways to consolidate their power while pretending to do so in the public interest -- and not their own and that of their cronies who benefit in some way from their decisions.
They miscalculated this time regarding how many people in America are paying attention to civil liberties concerns these days. And it is our job to make certain that they learn just how badly they have misjudged this.
UPDATE: Sen. Russ Feingold has a factsheet on FISA and why it's a bad deal for Americans.
