The government has done irreparable harm to these companies, because even if they are telling the truth, they will never be able to prove it (like Obama could never prove he wasn't born in Kenya) Each new bit of evidence supporting their position will be met with just more questions. That's the problem with government spooks, their capabilities are boundless, anything the mind can imagine, and there's simply not way to erase doubt. Can the NSA break public key encryption? No? Are you 100% sure? Does the NSA have a fibre-tap on all cables? Are they running continuous keyword searches on transcribed conversations of every American, in real time? Can you prove they don't have some secret new $30 billion data center, paid for by the $60 billion in Iraq money that went "missing"?
10 years from now, people will still be talking about this.
We need to roll back the Patriot Act, period.
