Florida’s Stand Your Groind statue allows the use of deadly force in response to great bodily harm, even if he does not fear his life is at risk.
That is correct. And what is the definition of “great bodily harm”? (I think it usually includes broken bones)
It also allows it to prevent any forcible felony (like rape).
It is a policy judgment, what things are bad enough that you can kill to prevent it. FL (and most states) say great bodily harm or rape or death. The only thing FL adds is that you don’t have to try to run away in those cases.
