“The Garland, Tex., shooting — the only example Comey used as an impetus to regulate encrypted technology — in fact makes the opposite point. Attacker Elton Simpson, who was under previous FBI terror-related investigations, used Twitter to openly follow and communicate with high-profile terrorists. His account was followed by prominent English-speaking Islamic State fighters and recruiters Abu Rahin Aziz and Junaid Hussain — both of whom for a long time were known to provide manuals on how to carry out lone-wolf attacks from Raqqa, Syria, before they were killed. Simpson also followed and communicated with Mohamed Abdullahi Hassan, a known American jihadist in Somalia who pledged allegiance to the Islamic State.”
