@Jeff: I don't think anyone was attacking him. It is a movie set, and for a lot of scenes, you have to point the gun toward the camera (to catch the scene). I think the cinematographer was behind the camera.
NOTE: I could be completely wrong about that - it's just that the facts of the situation aren't really out yet, only drippings of things (like the above), which could turn out to be incorrect eventually.
There are lawyers out there saying Baldwin should shut up and start to think more like a defendant.
