They say the one shooter who was killed was a military contractor named Aaron Alexis. Black guy.

Strong speculation is that he showed up with a shotgun, took out a security guard and got a 9mm, then took down a cop and got an AR15.

Reports from estranged family is that he worked with "Computer stuff". Victims say a white guy and a black guy in their 40s are suspected of being the other shooters.

This smells like a spook op went haywire and some small self directed cell opted to wipe out someone's operation in a loud and public manner punctuated by enough bodies to get international attention.

It apparently took place at the Navy Sea Systems Command Center.
