Mental
Mentally prepared to use inflict violence and shoot that gun at a moment of need
Take on the borden of taking the life of another in order to save others
Constant vigilant watching the doors and knowing the exits (facing the door when sitting in a restaurant)
Do not perish with the last words “only if I had brought my gun.”
Thinking, replaying the scenarios, mentally so that one will not hesitate when that moment arises
