In the wake of the Navy Yard shooting, Defense Secretary Chuck Hagel is ordering two separate reviews of security at U.S. Defense facilities world-wide -- one from the Pentagon and the other from an independent panel.
Meanwhile, more details are emerging about the mental problems of slain shooter Aaron Alexis.
We know that Aaron Alexis had been receiving mental health treatment from VA hospitals since August, and that he suffered from a host of serious mental health problems -- including paranoia.
Despite this, and several run-ins with the law over the years, the Defense contractor was not stripped of his security clearance.
What are the warning signs that a person might be suffering with mental health problems? Dr. Linda Mintle, a licensed family therapist and author, answers this and more on CBN Newswatch, Sept. 18.
That clearance allowed him to enter the Navy Yard with a shot gun and kill a dozen people.
"Mr. Alexis had legitimate access to the Navy Yard as a result of his work as a contractor and he utilized a valid pass to gain entry to the building," Valerie Parlave, from the FBI Washington office, said.
Consequently, this unfortunate reality has left many questioning their safety.
"Our people deserve safe and secure work places, wherever they are," Hagel argued.
Hagel is hoping that two separate security reviews will reveal the department's security gaps.
A new Pentagon report, which was underway before the attack, reveals a problem with the screening process for contractors.
The Inspector General found convicted felons routinely gain access to military facilities.
The president, meanwhile, wants Congress to revisit gun control legislation.
Alexis bought a shotgun and 24 shells two days before the shootings.
"The fact that we do not have a firm enough background check system is something that makes us more vulnerable to these kinds of mass shootings," President Obama said.
Alexis' mother revealed an audio statement saying that her condition is fair.
"I don't know why he did what he did and I'll never be able to ask him why," she said.
Authorities are still probing to learn why Alexis killed so many people, how he planned his attack, who might have helped him, and what can be done to prevent another such tragedy.
