Bottom line? Let’s not make more of this than it is until we have more proof. And no that’s not being politically correct – it is being factually correct. If he’s a radical Islamist jihadi directed by an al Qaeda master (or some like scenario), then I’ll be the first to point that out and condemn it.
But at the moment, he seems more like a nutjob who took went over the edge and acted out violently. Until I learn more about him and what caused him to do what he did, I’ll continue with that tentative conclusion. Because that’s the only conclusion supported by the evidence right now.
