Michael McKean as a cop - uncredited cameo?

If you have this on dvd or tape, check out the cop who talks to Jodie Foster and Scott Baio from inside his cruiser, as he's starting to drive away - near the end of the film, when they're up in the hills looking for their friend in the woods. Looks and sounds exactly like McKean, but there are only one or two cops in the cast list (I'm guessing one is the black cop in the booking scene) and no mention in McKean's filmography - but if it was just an uncredited cameo, something he did as a favor to someone, there probably wouldn't be.
