Fort Hood Shooter, Ivan Lopez, had never been in military combat. He had not had homicidal or suicidal tendencies or indications. The number 1 reason why he opened fire was because he was on mind-altering drugs.
Ivan had just had full psychiatric evaluation 1 month prior and had no apparent risk of homicide or suicide. Thanks A TON psychiatrists, you really helped us out there *sarcasm*. In fact almost every single shooting has been by someone either on or withdrawing from prescription medication. Just a coincidence? I think not.
CCHR just released a documentary recently that talks about how War Veterans, including Iraq veterans, are being over-prescribed medication.
After you watch that, it is no mystery why Fort Hood happened: homicide-inducing mind-altering drugs.
