I hope to goodness that they learned their lesson at FT Hood in case another nut-job stars shooting our service men and women there. Surely there is someone armed and available at all times to shoot back!
Most bases have rules against having firearms on post by personnel. We had the head of the State Marksmanship Team get his vehicle checked and he had military and personal firearms in his vehicle. He had to have his supervisor tell the guards it was OK for him to transport them onto the base.
