Clearly the man against the window preformed( thats how you spell it right? never could getthat) an amazing feign death in order to frame the green alien because the money was counter fit. And the police man is just there for the lols. What if it isnt a real gun? Thats always fun too ya know.
Hmmm...i think that the Squidman and The Black Guy were making a money deal, and the Squidman got mad. He killed the other guy, and the Space Police guy came upon them, and chased after/killed the Squidman.
