Senterfitt’s ruling was based on Alexander’s decision to go back into the home armed with a gun.
“This is inconsistent with a person in genuine fear of his or her life,” Senterfitt wrote in her ruling
'Stand Your Ground' doesn't mean go and get a gun and then come back into the house for a confrontation. If you have gone already, then stay gone.
The basic intention of the 'stand your ground law' is that if you are walking down the street and a guy pulls a knife on you, you have the choice of responding with deadly force rather than running away. You don't have to kill the guy with the knife. You could, but you could instead tell him to get lost and let HIM run away, or you could tell him to put his hands up until the police arrive, or you could shoot him in the a non lethal way to incapacitate him rather than killing him if you are a good shot.
The law is not designed to let two unarmed ex's verbally assaulting each other in a private home take a time out while one goes looking for a gun, then returns to the house to take a shot at the other. Once you walk away you are no longer 'standing your ground'. If you come back you might be the one seen as the aggressor.
