Before 911 intelligence was much more compartmentalized. After 911 we were told that we could have stopped it if we had "connected the dots" through a central data warehouse.
Well we got our wish. Now our enemies have one-stop shopping for all of our secrets.
And with the lax security that allowed Snowden deep access who is to say that the NSA didn't also let in a deep cover Chinese and/or Russian and/or jihadi spy?
Maybe this whole Snowden thing is a cover for the NSA realizing they had inadvertently given access to all of one or more of our enemies and wanted to pin the blame on some low level figure rather than pointing their fingers at themselves.
You get it!!! Please read my post #34
