Just because, in my opinon, the jilted lover angle seems weak doesn’t mean Islamic terrorism. This could be a guy that was mad at the world and like in other school shootings was just out for revenge for percieved slights.
I agree with you. It is, in fact, more plausible. I don't rule out jihadists ... I'm just waiting for facts, none of which exist yet. OTOH, experience has shown that the "cry jihad" contingent on these threads is much more frequently wrong than right.
