Grocery store scene (spoiler)
I don't follow what's supposed to be happening here.
Ishikawa says that Batou was hacked and shot himself in the arm at the store. No matter how many times I watch that scene, I can't reconcile that claim with the action on the screen. His right arm is being hit by bullets as he's drawing his gun with that same arm. He's also drawing a gun with his left hand, and it's conceivable (though unlikely) that the last shot to his right (that knocked the gun out of his hand) could have been fired by the gun in his left hand, the first shots to hit him impact the outside of his right shoulder. There's no way he could have done that himself.
