Sounds like we both have had first hand experience with someone having a psychotic break. I am of the opinion that no amount of education is going to change the outcome.
With the situation at hand, what we do know is that this was not a break. This guy had been a resident of the casino from Sept 28th. He planned before hand to get a room that had a tactical advantage. He Planned to be able to maximize the carnage he could create.
In May this year, ISIS sent out a call to its believers to do an attack of this kind in Los Vegas. The instructions and recommendations mirror what was done last night.
It has been reported that this guy recently converted to Islam a few months ago.
So, in short, was this guy crazy? In my opinion , yeah. What amount of education would have made any difference?
