Not surprisingly the FBI is doing its best to minimize last week's beheading in Oklahoma. Consider the commentary on Alton Nolen's Facebook page.
From The Washington Post:
The Moore police said that Nolen had tried to convert several co-workers to Islam. Two federal law enforcement officials told The Washington Post that Nolen was a recent convert to Islam with a “provocative” Facebook page that included a photo of Osama bin Laden.
Yet these officials also said that the FBI had found no link to terrorism. They also said there was no indication that Nolen was copying the beheadings of journalists in Syria carried out by the Islamic State. Instead, the officials said, they are treating this as an incident of workplace violence.
