OK then, how come the plans for the Boston Marathon terror attack was not sifted out of this data? (NSA had been fully operational by then.)
You are assuming Obastard’s crew cares about the Boston Marathon bombing. Additionally, I would not suggest we have a perfectly functioning system going so they have to be selective about what they’re looking for. Unless the Boston bomber guy used the words “Tea” and “Party” together that info would have been back-burnered.
