I don't know if this has been discussed before. But in this article covering the creation of a new DOJ "Whistleblower Ombudsman", Mike Levine says:
In June 2011, Forcelli told the House panel investigating the matter that "grave mistakes" had been made. But when he voiced concern to supervisors, those "concerns were dismissed," he said.

I don't know why he doesn't just name Dennis Burke. What other procecutor in Arizona would launch a punative attack on someone who testified about F&F?
