Officer Dan

Officer Dan was a rookie cop in Unfair Science Fair, called when Teddy's inventions get stolen. When he plants evidence near the stolen inventions that the Science Fair Judge stole them, the judge is imprisoned and Dan presumably planned to re-steal the inventions. However, William visits the judge and sees the copy of the judge's walking stick and the judge's real walking stick at the same time, thus he believes that the judge is innocent until Dan comes in, planning to also frame and imprison William so he won't tell anyone. However, William takes the copy of the walking stick and hits it over Officer Dan's head, knocking him out. William and the judge are freed, and Officer Dan is imprisoned.
