Washington Navy Yard Massacre, Annals of Absurdity?

I am shaking my head in disbelief too, but given what is being reported, here is a cut-to-the-quick summary of what went on yesterday in Washington, DC:

A mental disturbed guy, who was taking meds and who the Navy booted for "a pattern of misconduct", walked onto the grounds at the Navy Yard, got a rifle from a safe on the premises, and proceeds to kill a dozen people.

You can't make this stuff up.  It's as bloody absurd as, after 9/11 a long-known Islamist sympathizer, who is also unstable, not only infiltrates the Army, but is hired to counsel other soldiers, is protected by higher-ups, and proceeds to go on a killing spree. 

Crazy, right?
