When McCloud bails Chief Clifford out of jail, Clifford's car is waiting for him at the curb. It would have been impounded and not just waiting for him on the street.
While in the hospital, one of the robbers breaks a window on the door to the children's wing so that they can see into the hallway. There are crossing diagonal lines in the glass indicating that the glass is reinforced with wire. However, whenever the camera does a close in on the robber, it also does a close in on the glass and reveals that there are no wires protruding from the edges of the broken glass, clearly demonstrating that the glass is in fact not wire reinforced.
