accepting market manipulation

sadly at last the Bank of england have accepted that manipulation and market abuse has played a significant part in our markets .

                  Sadly the  market supervision  departments at regulators and exchanges failed in providing "fair and orderly markets " . BUT WHY ?      They were told by many trading establishments  of manipulations yet over many years chose to ignore them ; now years later we accept that the abuse was rife !             Question : do we compensate the honest traders or perhaps ask them why they complained and how they knew of the blatant abuse ? Perhaps also one could ask why exchanges and regulators  totally ignored their pleas and finally can we investigate with a new neutral panel as previous ones were either uneducated or also guilty of abusing our markets ?
