They have to blame Snowden because nobody knows how the thing was planned and they are thrashing around for answers. They are assuming that the operation was carried out with radio contact and so forth. The fact of the matter is this could be a set of independent groups given different targets and told to carry it out. There would be nothing to surveil electronically except for phone calls and if you didn't have number to tap, then you got nothing.
Like the stingray that the FBI loaned to local police. Track like 50k calls in its radius I think, but if you don't have the number, the call you want just comes in like all the rest, so the machine is only good if you have a start up number.
Surveillance and electronic intrusion is worthless until you have something as a starting point. These politicians either don't know that which I find hard to believe after Watergate, or willfully ignorant to make themselves look good before they know what's going on.
