Plot summary
Kurt McVeigh, the right-wing ballistics expert with whom Diane has an on-again off-again relationship, is on trial for testimony he gave in a murder trial. Pablo Beltran, the accused cop killer in that case, was sent to prison partially based on McVeigh's testimony. When extreme misconduct by the DNA lab caused Beltran to go free, however, he decided to go after McVeigh knowing that a judgment against the expert would end the latter's career. In the campaign for state's attorney, as Eli decides how best to use a "Nannygate"-style political bombshell that might cripple Wendy Scott-Carr's campaign. Eli appears to be sympathetic to the nanny. Alicia helps Diane defend McVeigh and piece together the truth about Beltran's shooting. McVeigh proposes to Diane, but she turns him down.
