That sounds like a partisan witch-hunt to me. We've gotta move forward. What has passed is past. Accountability is a quaint notion that has no application to the modern state. Laws are meant to be used for scapegoats and the little people.

A witch hunt is when the primary motive for an investigation is for political gain. See all the fake "scandals" surrounding the Clinton administration including White Water in which millions were spent to find that no laws were broken. Here is a situation in which it is very obvious that laws, regulations and policies were ignored. When laws are broken within a governmental agency, the agency is broken. To willfully ignore law breaking even to "move the country forward' only allows the poison to take root and continues to cripple the government and keep it from fully acting as it should. An investigation would illuminate all what was wrong as U.S. Supreme Court Justice Louis Brandeis famously stated regarding corruption, "Sunlight is said to be the best of disinfectants." An investigation and prosecutions - if warranted - need to happen for the sake of the agency.
