<P> In 2013, Frank is the target of an assassination attempt by Hector Santiago (Omar Maskati), a mentally - challenged teenager of the Bitterman housing projects who is tricked by a member of the Los Lordes gang who declared war on the NYPD . The bullets miss Frank, but hit Mayor Poole, leaving him paralyzed and confined to a wheelchair . </P> <P> One of Frank's predecessors, "Crooked" Commissioner Connors, served time in a federal prison after his term as PC was completed and left him with more than one mess to clean up, including Officer Thomas Sculley (Warren Kole), one of four patrol officers who, a few months after 9 / 11, accidentally shot an unarmed Muslim teenager, and was acquitted of all charges and allowed by then - Commissioner Connors to keep his job . In 2016, Officer Sculley, who had kept his head down for the last 14 years and made great strides to atone for his horrible rookie mistake, passed the Sergeant's exam with flying colors . Frank was reluctant to promote him, lest tensions between the citizens and the police grow even worse and ultimately offered Officer Sculley a choice: transfer to another city (Long Island, Albuquerque, New Mexico, Boulder, Colorado, or San Diego were among the departments Frank talked to) or take his promotion to Sergeant and ride a desk at the NYPD Erie Basin Auto Pound in Brooklyn for the rest of his career . </P> <P> In the first season, Frank is well regarded and respected by his officers and his city, to the point where the Mayor felt threatened by his popularity; however, by season 6, public opinion regarding the police--and him personally--has changed so drastically that he gets booed off - stage while speaking at Columbia University . However, in season 7, new mayor Margaret Dutton affirms that his polls are better than any of the NY Mayors </P> <P> Frank was nearly served with a vote of no confidence by the NYPD rank and file in 2012 when he publicly apologized for the accidental shooting of a black man by a rookie patrol officer (Corbin Bleu) instead of waiting for the official report . </P>
