From MIT Technology Review (h/t Intapundit). A couple of salient points:
We are seeing the NSA collecting data from all of the cloud providers we use: Google and Facebook and Apple and Yahoo, etc. We see the NSA in partnerships with all the major telcos in the U.S., and many others around the world, to collect data on the backbone. We see the NSA deliberately subverting cryptography, through secret agreements with vendors, to make security systems less effective. The scope and scale are enormous.
... The NSA’s actions are making us all less safe. They’re not just spying on the bad guys, they’re deliberately weakening Internet security for everyone—including the good guys. It’s sheer folly to believe that only the NSA can exploit the vulnerabilities they create. Additionally, by eavesdropping on all Americans, they’re building the technical infrastructure for a police state.
We’re not there yet, but already we’ve learned that both the DEA and the IRS use NSA surveillance data in prosecutions and then lie about it in court. Power without accountability or oversight is dangerous to society at a very fundamental level.
