German news outlet Spiegel published a story about the NSA’s ability to crack encrypted forms of communication, exposing the agency’s routine interception of SSL/TLS, which are used by web servers to transmit sensitive information. The report also exposed the fact that the agency has the ability to decrypt a virtual private network.

And from those 10M * 2 years * 265 days per year intercepts the NSA has prevented exactly zero, zip, nada, not one terrorist attack. Gosh! I feel so much safer - well congress apparently feels safer from us!
