Whitehurst's whistleblowing in the 1990s and the adverse publicity trials, in which FBI Lab employees were revealed as incompetent or disingenuous, led to major changes. According to John F. Kelly & Phillip K. Wearne's book "Tainting Evidence: Inside the Scandals at the FBI Crime Lab" (1998), the FBI Crime Lab had been hurt by a lack of funding and an institutional entropy rooted in Lab employees' belief that they were the best forensic experts in the country, if not the world. Some Lab employees failed to keep abreast of developments in forensic science.
