tip of the iceberg
They are only touching the tip of the iceberg. If you notice closely the surnames of most of the accused seem to be of people mostly originating from the Indian subcontinent. Figures that the grandstanding regulator agencys to save their own complicit skin and to seem relevent are going after less powerful more easily demonized brown people. After all the amounts involved are small potatoes compared to the massive amounts the white aholes at Goldman are stealing from the public. But then again white aholes tend to have powerful friends and vote Republican.
