Navy Yard shooting raises background check questions
WASHINGTON - The mass shooting at the Washington Navy Yard yesterday is raising questions about background checks.
Officials say the alleged shooter, Aaron Alexis, used a valid pass to get into the Navy Yard building where he killed twelve people. He was killed in a gun battle with police.
Alexis was an information technology employee with a defense contractor. But officials say he had been hearing voices and was being treated for mental problems in the weeks before the shootings.
Despite that, he was able to keep his security clearance.
Alexis was given an early, but honorable, discharge from the Navy in 2011 because of insubordination and other problems.
