That's the entire problem with this NSA crap. Anyone who bucked the system and made it far along enough in the process would have tons of dirt on him/her already automatically unearthed by the NSA's data centers. The info would be leaked to a complicit media, who would drool over the chance to run another political scandal, and the good politician's career would be over before it even began.
It's sad, but knowing about the extent of the abuse has actually made me *more* worried about protesting the abuse. Panopticon and all that -- we know they can be watching any of us now, with access to basically all our information online (even stuff that's encrypted, like this data, which is being sent over a VPN but who even knows if it's secure?), as well as all the metadata from our phones, which tell them exactly where we have gone. I doubt they are interested in me per se, but say I ran for office under a platform the established powers didn't like -- they might get interested then, and I would be fucked.
This shit is really scary.
