I would like to clarify that he didn't have a gun license nor did he show any interest in weaponry, not once did I see him reading the anarchists cook book, not once.
He was a big Kubrick fan, to the point of obsession and he had just amazon-ed Ark of The Covenant... I think he might of been inspired by the film... He changed after seeing it. The Roman breastplates were nowhere to be seen around the house. Instead, he started talking about the Aurora shooter and dying your hair with Cola in the name of the ark of the covenant, ok I admit that was a little weird but he did take acid when he was in college so, I thought he was just having a flash back. Apparently, I couldn't of been more wrong.
I don't know anything about Jesus Campos and his involvement in my dad's murder but I wouldn't doubt for ONE SECOND he was CIA. I watch the X-files, I know the government is hiding stuff and not just the body of my father. Most likely aliens and crop circles bigger and more intricate that any we have ever laid eyes on. My Dad would of liked to have seen those but now he is dead.
Just think carefully about what you let your parents watch. What happens in Vegas ends up on The Internet now, times change.
There is no going back from mass murder.
