A few years ago I worked on a documentary that sorta delved into Fusion centers. The doc itself was crap and poorly directed and whatnot, but, it uncovered some of the info Snowden revealed.. before he did… that all these centers are storing vast amounts of data on everyday citizens… like all your travel itineraries, which hotels you stay at, etc.
Also uncovered direct evidence Eric Holder was covering up the FBI's mismanagement of a very innocent woman they accused of being a terrorist.
