Robin is a master hacker, a fairly sharp detective and Batman is in charge of the League so if Batman knew something, Robin would have that information to work off of. Just to clarify here, and again, I don't know what continuity you are operating off of, but none of them have Nightwing 'turning against' Batman. Batman has fired him for spending too much time with the audience or Dick simply out-grew the position of Robin.
