What have we said on this forum many, many times? He who calls 911 first is the victim and the other guy is the BG.
From the few details here, it appears the guy acted in self-defense.
It sounds racist to say it, but I will also tell you that, should you be forced to use your weapon in self-defense against a member of any minority group, you had better have a good audio/video recording of the incident, friendly witnesses, and an extremely good lawyer. A lot of money wouldn't hurt, either.
