A report by the investigative team over the 2013 Washington Navy Yard shooting spree by an employee recommended the strict reinforcement of laws and regulations that emphasize the need to report potential threats and problems in their organizations.

Aaron Alexis, the Navy Yard shooter responsible for killing 12 people last week, lied about a previous arrest and failed to disclose thousands of dollars in debts when he applied for a security clearance in the Navy. Federal investigators had dismissed the omissions, all the while deleting any reference to his use of a gun in the same arrest.

Cathleen Alexis, the mother of Aaron Alexis who killed 12 people in a rampage at the Washington Navy Yard, apologized publicly on Wednesday, expressing that her "heart is broken," and could not explain her son's deadly actions
