The blog post links to the indictment on Scribd, which wants you to pay for access, but it's freely available through Wired. http://www.wired.com/images_blogs/threatlevel/2012/04/WILLEMSIndictment-FILED.045.pdf I've been skimming through it, and virtually all of the charges against came from "coded language" in their emails. It's a stunningly long and detailed list, but the charge that will put them away for a long time is 63 grams of LSD. And yeah, all that could have been avoided with PGP.
