What constitutes a pernicious scheme to induce a witness to testify in a criminal case?

My respected colleagues describe this case as involving a simple failure to disclose part of the plea agreement. I see it as more than that: It involves a pernicious scheme without any redeeming features, a scheme that can only spawn unnecessary post-trial motions and appeals when its presence in a case becomes known to the defense. The scheme violates both the letter and spirit of Giglio v. United States, 405 U.S. 150, 92 S.Ct. 763, 31 L.Ed.2d 104 (1972)(A prosecutor must disclose to the defense any inducements to a witness to testify.).
