The AP reported today that Tamerlan Tsarnaevm, the man accused of being the mastermind behind the Boston Marathon bombings that killed three people and injured 264 others, “took an interest” in Infowars, Alex Jones’ website, as well as a myriad of wild conspiracy theories. According to Elmirza Khozhugov, who is Tsarnaev’s ex-brother-in-law, he was fascinated with anti-Semitic conspiracies and was even after a copy of one of the most famous (and absurd) conspiracy books of all time, “The Protocols of the Learned Elders of Zion,” which alleges that Jewish people are secretly planning world domination.
