According to POGO, in the prior two years, the SEC had taken no action on 27 out of 52 recommended reforms suggested in Inspector General reports, and still had a "pending" status on 197 of the 312 recommendations made in audit reports. Some of the recommendations included imposing disciplinary action on SEC employees who receive improper gifts or other favors from financial companies, and investigating and reporting the causes of the failures to detect the Madoff ponzi scheme. In a 2011 article by Matt Taibbi in "Rolling Stone", former SEC employees were interviewed and commented negatively on the SEC's Office of the Inspector General (OIG). Going to the OIG was "well-known to be a career-killer". Because of concerns raised by David P. Weber, former SEC Chief Investigator, regarding conduct by SEC Inspector General H. David Kotz, Inspector General David C. Williams of the U.S. Postal Service was brought in to conduct an independent, outside review of Kotz's alleged improper conduct in 2012. Williams concluded in his 66-page Report that Kotz violated ethics rules by overseeing probes that involved people with whom he had conflicts of interest due to "personal relationships". The report questioned Kotz's work on the Madoff investigation, among others, because Kotz was a "very good friend" with Markopolos. It concluded that while it was unclear when Kotz and Markopolos became friends, it would have violated U.S. ethics rules if their relationship began before or during Kotz's Madoff investigation. The report also found that Kotz himself "appeared to have a conflict of interest" and should not have opened his Standford investigation, because he was friends with a female attorney who represented victims of the fraud. According to former SEC employee and whistleblower Darcy Flynn, also reported by Taibbi, the agency routinely destroyed thousands of documents related to preliminary investigations of alleged crimes committed by Deutsche Bank, Goldman Sachs, Lehman Brothers, SAC Capital, and other financial companies involved in the Great Recession that the SEC was supposed to have been regulating. The documents included those relating to "Matters Under Inquiry", or MUI, the name the SEC gives to the first stages of the investigation process. The tradition of destruction began as early as the 1990s. This SEC activity eventually caused a conflict with the National Archives and Records Administration when it was revealed to them in 2010 by Flynn. Flynn also described a meeting at the SEC in which top staff discussed "refusing to admit the destruction had taken place, because it was possibly illegal".
