S19, E13: A war widow with a possible grudge against the Army, Carly Di Gravia (guest star MacKenzie Mauzy), is found unconscious in the rubble of an Army Recruitment Center along with her lifeless infant. As detectives Lupo (Jeremy Sisto) and Bernard (Anthony Anderson) search for the bomber, they encounter Megaphone Bob, the leader of a group of war protesters, including Charles Cavell, whose sister was killed in Iraq. The detectives must also deal with the confusion that arises when "Operation Molly," a couple of fanatic citizens who like to work with the police to solve cases, gets involved. ADA's Michael Cutter (Linus Roache) and Connie Rubirosa (Alana de la Garza) efforts to bring the bomber to justice are complicated by potentially compromised evidence, reasonable doubt and public sentiment. DA Jack McCoy (Sam Waterston) must make one of the most unpopular decisions of his career. Also stars S. Epatha Merkerson.
