Well there's no way Kiriyama is going to survive a shot through the head like that.
I'm still mad as hell at Kawada for not making sure that fucker was dead though, especially after Kawada did well to make the sports car explode and trying to make sure Kiryama was dead earlier. that made it a bit strange to me that Kawada just shot him once from a good distance and assumed he was dead? yeah okay.
