Although I agree this should have been judged a case terrorism, I think Munley's case is suspect. She was clearly working for a private contractor, so she was not a member of the military. As such, She is not eligible for the Purple Heart (PH). As of 1997, no civilian employee, or contractor is eligible for the PH.
I have a suspicion that something else is going on with Ms. Munley and perhaps the others bringing this lawsuit. First, of course is the shark lawyer, egging them on. But, I think if we had any good investigative journalists left, they may find that after her heroic actions at Ft. Hood, she may have become too full of her hero status. Maybe pushing her private employer too far.
