The investigation of a neighborhood monster isn't too weird for the crew of Cops (1989) to follow around Mulder and Scully.
An investigation into possible Werewolf sightings brings Mulder and Scully to Los Angeles. There they run into a crew filming a 'COPS' episode. While being followed around by the 'COPS' camera crew, Mulder and Scully trail a monster that appears to be able to change into each victim's own worst nightmare.—firefly_andy
