he’s been a gambler for 25 years and now is feeling angry and under appreciated even though they give him free big suites, cruises, and hookers. Yes the casino even springs for his prostitutes.
I don’t think he’s mad at the casino for not recognizing his video poker prowess.
Right, not mad at casino’s. He is mad at the world in general. He made millions, but never was a boss in a corporation, or a businessman with employees, or a well known politician or a celebrity. So basically no one respected him. He also seems to have had no luck with ladies. His long time Filipino girl friend can not be called hot, by any stretch of imagination.
Now by killing 58 people and injuring 500, in his twisted & frustrated mind, he is telling the world, look how intelligent I am!
