The "posties" lost that when they listened to this guy, or stories about him, and said nothing.
None of the good Major Hassan stuff showed up in regular stories, but they went after the commanding officers like they were monsters.
There's reason to believe the "posties" (all of them or some of them) KNEW or had REASON TO KNOW that this guy intended to kill people.
It is not unreasonable to believe that they, themselves, were part of a conspiracy to assist.
Regarding matters that directly and exclusively
belong to the military and effectiveness of
leadership and their procedures .. that’s
a far out connection. The military are mandated to
be responsible for matters concerning the troops.
The ‘posties’ operate at their whim and ideologies.
