Yeah, the first time I watched it, I was getting ready for it.
I was all pumped, and then I was like, "How is he going to just segue into shooting these kids after getting jiggy with it? It's going to have to be a pretty smooth motion so they don't all run away or move. He'll probably only be able to get a one or two because I know they'll scatter away after the first shot."
If you think about it, that wave is the only move that you can put your hand on your sidearm and actually pull it off without people really noticing it.
