It wasn't temporary insanity. But it was definitely a "heat of the moment" murder. You're not supposed to give somebody a life sentence for something like that, so the ruling was still unjust. Even though he went into another room and grabbed a gun, I still feel it was "heat of the moment", because emotions can easily run high even for a prolonged period after a robbery takes place. He should have gotten 20 years at most. At most. But I heard the robber was black, and some are claiming the owner decided to "finish" the robber because the robber was black, not because he was a robber.
