ASHCROFT TESTIMONY

When the OIG says that there have been cases of abuse, and you investigate 14 of 18 cases of abuse but find that exactly zero cases (so far) merit criminal charges, what has the response to the OIG report been? Or, to put it another way, if the OIG shouts into a forest and no one is punished, has he made a sound? I'm not an expert on this issue, so I don't really know how often criminal charges are brought pursuant to OIG reports. (Testimony is on C-Span)
