Corrected entry: When the guy shot Stu's ear, the police oficers could have determined where the bullet came from by imagining a line linking the two holes in the windows of the phone booth. It wouldn't necessarily be hugely accurate, but it would identify the building it came from.

Correction: There's only one pane with a hole in it. The pimp broke the pane facing the street which is where the bullet entered.
