The answer is to do both. You can have a political debate about freedom and come to sane conclusions. Ten years or one terrorist attack later and you're back having the same debate with a possibly different conclusion. And don't forget, every country in the World would need to have this debate. And I'm pretty sure, countries will always consider the surveillance of people in foreign countries fare game if they can get away with it. The US and the UK (my home) certainly will. We should strive for technical solutions which make mass surveillance either impossible, or more realistically so expensive it becomes infeasible. Money talks.
