Easy access with a high vantage point overlooking a target rich environment ensuring maximum carnage. I think he was a deeply troubled person with serious issues that will come out that triggered him to snap like a twig in a hurricane. Proof that wealth is not necessarily the key to happiness.
I disagree. With all the planning and logistics being involved, this guy's brain did not just wake up psycho one morning. This was as well planned as anything the Jihadists would do. Not saying he is of their ilk, but he put a lot of thought into this, and had a specific date and target in mind.
Personally, I think he is just one more crazed anti-Trumper.
“Wealth” in this case ( I believe ) translates to a “high roller”. That is, he dealt in wealth but with great risk. This is in fact a syndrome ... “doubling down” ... You keep raising the stakes, so you can exhibit the apparent fruits of wealth at increasing levels until your obligations catch up with you. It’s an old story, and I surmise that it is the story in this case, as I’ve posted earlier.
