He might have had something to do with it--OR, it could be that he's not all that "lone wolf" at all. I suspect the latter.
The school threat was in the form of a letter sent to one of the schools (as I understand it). It was decided to close all the schools that Monday, and continue a police presence later, as a precaution. If this raghead was involved, then the Feds likely know it, yet I've read nothing to indicate his involvement. Thus, I'm skeptical. The only thing that relates the two stories is the timing. But, it does make me wonder.
I found the school threat interesting because our police chief spoke at our weekly Kiwanis Golden K meeting on Thursday, then the Sunday paper contained the news of the threat and the intended closure of schools on Monday. He sure kept a straight face during his speech, yet I'm confident he had to know on Thursday of the threat. I have to give him credit for his professionalism.
As to his 'lone wolf' status; it's possible, but as my wife said this morning, his friends have to be pretty bugged out right now. They're certainly under observation as well. Who knows what will turn up.
