This is almost at the end of the Sun-Times story about feds investigating Blago and friends as in letter to AG Lisa which she released, we assume partly to cover self for not continuing to pursue them with her own investigation. Such as it was, we are tempted to say:
The release of the letter was not viewed as a positive development within the U.S. attorney's office. While publicizing an investigation can bring potential witnesses forward, it can prompt people to shred documents, get lawyers and get their stories straight before investigators visit them.
Maybe this should have gone higher in the story?
