District of Columbia Navy Yard Shooting: Why?

Dead Shooter:  Why did he do it?

Good advice from TOM.  It is still unclear what really happened, let alone know why it happened.

RIP to his victims.  My prayers and condolences to the surviving victims and the victim families.

Update:
Mental Illness?
Then there is this: He believed that mediation would give him wisdom...
I don't like Mondays...
What ever happened to crazy?
The cops warned the Navy he was unstable six weeks ago?
The signs were there but no one put them all together...
Shooter was an Obama supporter (back to you Piers and Brian Ross...)
What did the Navy know and when did they know it (I see a big lawsuit coming...)
Was an elite cop team told to stand down?  If true, what did they think, this was Benghazi?
Alexis was becoming increasingly unstable prior to the Navy Yard shooting (no one connected the dots).
