Authorities are having trouble with motive behind the Las Vegas shooter.  None of the usual apply.  Here’s a comfortable white guy, no criminal history or history of violence, relatively wealthy, stable, has a girlfriend.  Not political or religious, not angry.  So why did he do it?  Maybe they’re looking too hard. Maybe the truth is more frightening yet.  Instead of fringe, maybe he was mainstream.  Maybe, like the masses, he was just bored.
