From "it's only to catch terrorists, guys" to potentially "it's also used to prove guilt in minor domestic cases." I, for one, hope this succeeds. Maybe then we'll have a way to get the masses to understand just how bad this surveillance state really is, for all of us.
It's only a matter of time until this data is used for political means (see the recent IRS story). All it will take is someone coming into power that threatens the agency or its valued partners in any way. Then out comes the embarrassing tweets or tax evasion evidence pulled from Amazon. This will only become more easy as the young people of today become the Senators and Presidential candidates of tomorrow.

How about some ambitious sys admin from Booz Allen or otherwise sell the information to HR departments, the Enquirer, The Daily Mail, Goldman Sacks, the Chinese, the Russians, or start his own "protection business"?
