I would love to know how they got caught. There is probably something to learn about opsec from this.
The paranoid side of me says Tor is unsafe (due to whatever - the authorities having backdoors on most hosting services, on your PC, due to the encryption being cracked by some unknown breakthrough or due to 90% of entry nodes being controlled by NSA). And NSA and FBI and co just have hundreds of people working on "parallel construction" of evidence.
Of course, a blunder by the operators is much more likely...
