Question: Beginning with the "Convicts at Large" episode in season 3, full width window boxes appear at the bottom of both front windows on the inside of the Sheriff's Office. Prior to this episode, they did not exist. Window boxes are often used to display decorative plants but I don't see any plants. And if they were supposed to partially block the background, the blinds were long enough to accomplish that. I find it hard to believe that the producers would spend additional money (for material and labor) for something that seems to serve no purpose. So why were they added?
