Oh, I didn't realize the perp was from Florida.
In Florida, it is a valid defense that if you feel threatened you can kill the person threatening you. If this had happened in Florida the guy would probably not face jail time.
Unequal laws. Should be interesting.
It isnt that simple. In florida you dont have the requirement to retreat, it doesnt mean you can actively go and just shoot someone/punch someone down.
The person also has to be attempting to threaten bodily harm, not just insulting you.
The difference between the required retreat and not requiring retreat is given by this example.
Say you are in a dead end alley, and someone is charging at you. in all juristictions you are then permitted to fire on them, as you have no real escape options and there is a chance of bodily harm.
Change it to an open alley, where you have a method of escape. In this case if the law requires you to retreat you have to, exhausting all options before using deadly force.
That being said, if the other person is also armed with a firearm, then your requirement to retreat is not really enforceable, as any flight would leave you open to gunfire.
