Effect of FBI Reprioritization on Public Corruption Prosecutions

It's no surprise that federal law enforcement agencies, including the FBI, reorganized their priorities after the 9/11 terrorist attacks. An audit from the Department of Justice Inspector General describes the effect on the FBI. Here's a summary from the section of the report discussing the effect on public corruption cases:

Although public corruption is the FBI’s fourth highest national priority, the FBI utilized fewer resources in this area in FY 2004 than it did in FY 2000. This decline resulted in fewer case openings during FY 2004 and less activity in public corruption cases, as evidenced by the 23-percent decline in case serials. Additionally, the FBI’s reduced investigative efforts corresponded with fewer public corruption matters referred to the USAOs.

Has there been any effect on ethics prosecutions of federal employees for serious violations? I'm not in a job where it's easy for me to see overall trends, but for what it's worth, I haven't haven't seen any egregious cases that should have been criminally prosecuted but were not.

A recent Seattle-Post Intelligencer story describes that paper's view of the overall effects of law enforcement priority shifts. A GAO report found the evidence of harm to other national priorities inconclusive.
