Try Hasan and his chains of command for treason first.
Say.....Hasan admitted he changed sides & committed mass murder while in uniform as a secret `soldier of Allah’, didn’t he?
That’s espionage AND treason right there, isn’t it!!!?
Anyway, this conviction should give standing to all the family members of the dead & wounded for an avalanche of wrongful death lawsuits against Hasan, and the military can now begin considering criminal negligence charges against his chain of command (but probably won’t).
The chain of command can still be sued, I would think.
I wonder if Obama is so stupid or arrogant as to publically refuse to sign the execution order (he probably is).
