Tonight, "Piers Morgan Tonight" welcomes Dr. Michael Welner and Dr. Mehmet Oz for an insightful discussion inside the mind of a killer. Welner, a forensic psychiatrist at NYU Medical Center, says the shooter's behavior in the Sandy Hook Elementary School massacre was disgusting. "This is an indefensible act," he says.
"If we don't collectively, in the press and leadership, say 'this is disgusting, this is repulsive' but rather to say 'who failed him?' then everyone who has a grievance, like him, who nurtures it and then says finally 'I want my grievance to be heard because I'm anonymous' there is an incentive for relevance and there is a vehicle for escapism of video game immersion who want to be deadened to crawl in the cracks and stay there where no one can discover them until it's too late."
Oz, host of "The Dr. Oz Show" is more concerned with mental health than guns in America:
"We need a homeland security approach to mental illness," Oz says. "In psychiatry - hands are bound. So many rules govern what they are allowed to do it makes it almost impossible for them to be able to provide that type of broad scale support."
