The Prosecution of Salvatore Maroni

Harvey Dent arrives in court to join Rachel Dawes in prosecuting mobster Salvatore Maroni, the alleged new leader of the Falcone crime family. One of Maroni's men takes the fall in court, and attempts to shoot Dent from the witness stand. The gun doesn't go off and Dent punches the man before he is hauled off to jail. Maroni is eventually set free, to the dismay of Dent. 
Dent meets Lt. Gordon, and after a short exchange of words, they both express their distrust for those that are working in each other's offices. Harvey interrogates Gordon over his involvement with the Batman and Harvey tells him he wants to meet him. Gordon requests search warrants for five banks that are believed to be holding the remainder of the mobs money. Dent agrees to back Gordon's search warrants, forming a tenuous trust with the honest Gordon, who in turn hails Dent as Gotham's "White Knight" while Dent questions Gordon about another nickname they had for him when he was at I.A.D., a nickname Gordon claims to have no knowledge of.
