Oh man, I saw this set a long time ago, and it's so hot. The guy is still alive and he's crawling away (and very cute too!), and his new sneakers are sexy. I think the guy with a gun is a police officer. So two guys, probably drug banditos, are lying dead in the street, and one is shot and bleeding, and trying to crawl out of the way. Everyone is standing around not really doing much of anything. Then the PO goes over and straddles the alive guy, which itself is pretty damn hot, and points the gun right at him.
I don't think he actually finishes him off, though I wish he did. But he's losing tons of blood, and probably didn't last much longer. All in all, a very sexy scene!
