Criminal Minds: A.J.Cook plays Jennifer "J.J." Jareau, the press liaison on the CBS drama "Criminal Minds." She sees her character's use of a deadly weapon as a sign of additional responsibility in the third season of the show. Strapping on a bulletproof vest and storming a house or a building is all part of the fun for Cook, who sees J.J. as a go-between for the team and the public.
