FBI Agent Apparently Egged On Garland ShooterIf you read into nearly any story of somebody arrested for terror links in the USA, you find out that the FBI supplied them with fake bomb materials or in some way heavily encouraged them. Sometimes these people are of questionable mental competence, and in my opinion shouldn't be prosecuted.
It's seemed likely for a long time that this pushing would be involved in real violence one day, and in the article above we learn that an FBI agent texted Elton Simpson, who shot up the Muhammad cartoon contest in Garland, Texas, "Tear up Texas" shortly before the event.
(Fortunately Elton Simpson did a bad job and the police did a good job; he and his partner were the only deaths or even serious injuries.)
