... Well, your sound do suck!
It's an OK flash... but you're having problem with sounds... Not just because of your crappie recorder!
I can't tell the difference between your policemens with voice only.
Try to imply someone else in voice acting if possible or do something else...
Also, it's good that you begin with some background sound but all the flash should have some. It was strange that at somepoint the background ambient sound cuts for nothing at all... Also, the background loop at the beginning seems syncuped you should do something about it too!
Also, the character are very statics... they seems like if they all suffer from some paralysis. I think you could remove a little bit of staticness by making the eyelids move (maybe by adding some eyelids to begin with would add some realism to your characters).
Also, maybe if you would make something with their arm that would be good. It's very strange... (BTW did you ever see a newsreader with his arm under the table?).
That's all for now... good luck in the futur!
