As much as I dislike excessive surveillance, it's worth pointing out that defenders of free speech far outweigh proponents of gathering data for eavesdropping. Of course, the USA enjoyed free speech before the internet existed. It's one of our strongest values. I partly grew up abroad and have friends in numerous countries where people do not have the right to speak their mind, and this should not be taken lightly. Again, I am not a fan of the extensive surveillance, but the "good track record" does not have its foundation in eavesdropping.
