Tor and shit is still a thing for terrorists... I mean in the west where everyone has an official adress and all it cant be too hard to find the one that a specific IP belongs to, but if someone in Syria connects to some antenna in the middle of nowhere, the only thing they know is that he was somewhere in the vicinity of that antenna at the time. I really dont think that that out of all the strange things going on around daesh is the one that should alert us that theres something fishy going on...
