Conspiracy in Aurora

  OK, maybe there is not one.  It does get attention though doesn't it?
I was reading an article yesterday concerning the shooter in Aurora.  The article seemed to be a little out there at first, but then it does raise some questions I would like to hear answers for.
  The news says that this guy was a really smart student and had a great future going.  In fact the only thing they had a record of him for was a traffic ticket.
 The equipment he used was not cheap.  The body armor is expensive if you can get it.  The weapons are not cheap, and a lot of ammunition costs a lot of money.   At least more than is available to most students.
He had never been in the service, so where did he get any training for this stuff?
Maybe ther is nothing to this, but it is curious.
