Jenkins lawyer, Dennis Lieberman, pointed out that a small section of the Castle Doctrine applies to people who are invited guests.
“I’ve been practicing law for 41 years and you don’t often use self-defense because if you miss just one of the elements, if you could have retreated, if you use excess force, if you’re the one that started the fight, any of those can impact self-defense.”
Lieberman says self-defense is complicated and not an easy defense to use because there are three different subsections of the law. In this case, Jenkins was protected by it.
Since the defender was allegedly hiding in a closet before he was attacked, I doubt he was able to retreat anyway, castle doctrine or not.
