“mass casualty events, such as the shootings by an Army psychiatrist at Texas’ Ford Hood in 2009 that left 13 people dead.”

Kind of burying the story here… Fort Hood has had MULTIPLE shootings.

(Why yes, yes he did use his personal firearm)

(Also a personal firearm, bought from the same store the previous shooter used.)

Sounds like preparation for a coup d’état.
