Yeah, the shootout is annoying when elite forces miss nearly every shot, especially from this distance, i can understand shooting on a moving car is harder, but still, I would use a pistol to fire at tires over any automatic side arm, teh spread is just not worth the attempt.
I can understand why Chinatsu went commando for better aiming, the state of being commando increases adrenaline and improves self-focus, a side effect of that could be better aim, pretty interesting, I'd like to see this tested in real life, i'll even try it when I'm back at my old home in august, there's a firing range not too far (around 6 kilometers from my old place I rented out for half a year to students) so i'll take my gf who never fired a gun and tell her to try normally, and then i'll tell her to remove her pantsu and try commando. I'll expect a slap on the face faster than the speed of light though XD but who knows, she might actually do it XD
