When the flyer is tossed into the gutter at the end of the show, the gutter is filled with flowing water, but the sidewalk and pavement all around are dry.
As Gannon and Friday are leaving the location after talking to the suspect, Gannon is carrying a flyer in his hand advertising what the suspect is offering to those who are interested and sharing some of his teachings. As the two officers stop at the curb and converse briefly, Gannon wads up the flyer and tosses it into the gutter. The flyer is seen landing in a small stream of water and floating away. Friday says nothing to him as they head to the car. This would be unusual behavior for two seasoned officers, especially detectives, since this is obviously blatant and intentional littering, by someone sworn to uphold the law, even though it would be a misdemeanor.
