Frank gives Officer Clark a summons for littering when he catches him smoking on the job and throwing the butt on the sidewalk. He was also texting while on the job and is disrespectful to the Commissioner. He feels he shouldn’t get a summons because he’s one of “the good guys.”Later a cartoon is circulated of Frank with a rolling pin in one hand and a summons book in the other with the caption, “Nanny on the Loose.”

Even Danny and Jamie talk about what a good cop he is but that he frequently feels persecuted by authority. 

When Officer Clark decides to take a transfer to Long Island, Frank visits him in his precinct and tells him that that is unnecessary if he’d like to just put this behind him. Clark salutes Frank as he leaves.
