If you think all radical islamic terrorists live in caves in deserts (or even...many of them?) you are painfully naive. Yeah in general I think they have shitty computer skills, but they certainly have some forums that know about Tor etc. The 95% accuracy claim is true, I don't see why you doubt it since you don't apparently know anything about the technology. Yeah it did take them for ever to find Osama. Honestly makes me question how hard they were looking.
