I'll say bad perspective, as I doubt Obama would push a grandfather's clock onto a dead Secret Service agent. That would be adding insult to injury, and our president doesn't strike me as a guy that would do something like that.
Also, it seems Obama is ambidextrous - note how the gun keeps switching hands (amateur night, Liefield!). I wonder if on the next page, Obama holds his gat on it's side when he fires, like his g's in tha hood would? It's possible, note how grim Obama looks once he gets the gun - all moody and all business. Yeah, somebody's gonna get a steel-jacketed stimulus up in here, up in here.
What's with the Bono style sunglasses the Secret Service agents are wearing? I've worked with the Secret Service before, and no way in hell would they wear shades like that. Indoors.
