America's expression makes it clear that there's a disconnect between his mind and his body. A steady hand raises the gun again, calmly aiming between Danny's eyes, while his face continues to mimic an overly nervous Chihuahua. If you've ever seen a Chihuahua freak out, you understand the expression perfectly.

"BECAUSE YOU'RE SUPPOSED TO BE GAY NOT A GHOST YOU CAN'T BE HALF GHOST BUT YOU CAN BE HALF GAY I KNOW BECAUSE I'VE BEEN THERE BUT YOU CAN'T BE HALF DEAD UNLESS YOU'RE A COMMUNIST AND YOU'RE NOT A COMMUNIST RIGHT??????"

The poor guys is having a meltdown, completely unaware that he's now charging toward Danny and firing off shots.
