This episode marks the second in a row to feature a veteran of the series The West Wing (1999), Bradley Whitford and Joshua Malina respectively.
This isn't the first time one of Danny Pino's characters has attacked a pedophile; as Detective Valens in "Cold Case", he beats up a pedophile hanging around a playground in a scene very similar to the final scene of this episode. Unlike Amaro, however, the Cold Case character did not face repercussions for the beating.
