This was the series finale. This episode was a take of the bank robberies in the Los Angeles area. In this episode several officers were hit in the line of duty and it was clear that the series was either changing directions or they the producers knew that the series was over and just left all of us to hang in the wind. High Incident deserved a much better sendoff..
