A newscaster refers to the shooting as having taken place on Broadway and Marcy Street. The location should have been referred to as Marcy Avenue. Several times other characters do refer to the location properly.
A same extra (man with dark glasses) can be seen walking twice on the shot with Kevin Calhoun making his campaign at the ending. First, Kevin gives a leaflet to the man, who accepts it and takes the subway route. A few frames later, the same guy appears but this time he refuses the leaflet and goes to the subway (again).
Coffins at NYPD funerals are covered with the NYPD flag which has 5 alternating green and white stripes and a field of blue with 24 stars in a circular pattern in the left, upper corner. They are not covered with US flags as in this film.
