Navy Yard Security Changes

The Navy is recommending three changes to security procedures following the Navy Yard shooting. It says civilian background checks done by the Office of Personnel Management should include available police documents. The service is sending Defense Secretary Chuck Hagel the recommendation for approval. Navy Secretary Ray Mabus has approved the other two changes. One will require executive officers or other senior members, rather than junior officers, to manage command security. The other would require more scrutiny at top levels of candidates' evaluations and fitness reports. Authorities pouring over shooter Aaron Alexis' record have found signs that he suffered from mental illness and was prone to violence.
