Oceans of data, drought of analysis
One of the things that bugs me about the NSA story is that the government has oceans of data available to it. The problem has been poor analysis. Data about Tamerlan Tsarnaev was handed to them on a silver platter, and they didn't see the threat. Major Nidal Hasan openly advertised himself as a jihad sympathizer, and blind eyes were turned.
What's the point of seizing this titanic amount of information about the phone calls of millions of innocent Americans when the government seems to have trained itself not to see certain threats?
