Swatting: Ghost In The Machine (1993) - Earliest example of Swatting I've noticed so far. The characters unplugged all the power so an evil AI (soul in the machine thing) couldn't get to them. So the AI/evil guy told all the different police cars that there was an armed robbery/hostage situation etc at a property, then when they all arrived, it overrode an electric pylon causing a bang which made them all fire into the house.
