I researched and wrote the article “The threat from ‘Minnesota men'” before the San Bernardino massacre, but the things I learned along the way may have some bearing on it. “Minnesota men” have been in contact with ISIS and sought to enlist in the cause. In April the FBI arrested six of them who were on their way to join the jihad. We’re a little ambivalent about the FBI’s success in apprehending them. Now they’re going to remain here and they really, really don’t like us very much.
