Didn't his mom say the police "got the right guy" as in, she knew he'd lost it? Clearly she, and likely many others knew that he was off the wall, or getting close.... same thing with the Loughner fellow in AZ. We really need to get better mental health services in this country, for our ailing servicemen, as well as the distressed citizen. The stigma around ptsd, depression, anxiety, etc needs to change immediately.... if it doesn't these tragedies will continue and it leads to stricter gun control.
