I like the animation
I liked how this has a ridiculous laughtrack as a way of mocking the overuse of those things. It was cool with how the laughing stopped when the police officer was shot. I thought maybe you would use the laughing for dark humor, but you did not. I also thought he was going to shoot the bum, but instead he gave the gun to the bum. At first the carnage is not shown with the first murder, but you change by explictly showing it later. It is a pretty good example of showing variety in your work.
