Couple of things:

I do think there could have been a better lighting effect used at the beginning for the police lights. They seemed a little too distracting, and I don't think police flashers actually work that way.

And even though you said the sound wasn't all that great, I think it worked well for the "copper chopper" that was flying overhead. The problem with the sound was that the lady's voice acting wasn't very good (it was too quiet, and she kept throwing unnecessary periods at the end of every other word) and it kept being overlapped by other voices, most noticeably, at the very beginning.

It was like:

"Suspect."
"Armed and dangerous."
"Proceed with cauthe special police."

I didn't understand the joke, but I did like how you built up a storyline around the joke, which is rare in your other episodes. Instead, it's always sorta random.

I think you could have done better on the last shot. It was a little all over the place.

Lastly, and a little more on the positive side this time, the animation was very good, as were the facial effects. I can only wish you the best of luck on future projects.
