Couple observations;
1. At the beginning; note the girl trying to waft the #@%! smell away from her face. Guess what lady - the bus always smells like that.
2. IMHO - Given that they overtook him, I'm confused how he was still alive when the police got there?
3. More of sidebar - does anybody know if those headphone cords that everybody on that bus was wearing are strong enough to strangle someone?

Edit: oh, OH, they should have recruited the individual who produced the 'item' being wafted by the girl at the beginning of the video, and had him, or her, sit on the criminal and 'blast' him!
