You can make that argument in the context of the judgment call. You cannot make that argument in the context of Florida law as what OP described was within the parameters of use of force law in Florida. I would argue that a BURGLAR approaching the homeowner with a deadly weapon in his hand is plenty reason for OP to be in fear of death or great bodily harm to himself or his spouse. Read the law.I’m suggesting if there are burglars in the garage and they are safely in the house, and they go out to the garage and use deadly force…yes…they would be the aggressor at that point.
Standing your ground is NOT the same thing as looking for a fight or using deadccly force when your life is not threatened.
