The independent contractor that hired Washington Navy Yard shooter Aaron Alexis knew he was showing signs of mental illness, but failed to report the finding—despite rules requiring them to do so, according to congressional testimony Thursday.

Stephen Lewis, a Deputy Director for the Office of the Undersecretary of Defense told the Senate Committee on Homeland Security and Governmental Affairs that it was determined that the company, The Experts, was well aware of Alexis’s mental instability and failed to report the information.

I suspect The Experts will be sued into oblivion over this revelation, and feel little pity for them.
