Good thing that NSA is collecting all that metadata

ISIS has figured out how to make that irrelevant:

ISIS figured out that if you give a leader resources, a target, and a time to get it done, then tell him to get it done however he can, you will get big, nasty and above all successful terrorist attacks in western nations, because such methods do not require detectable electronic communications.

But at least it's good for identifying the Administration's potential enemies, amirite?
