because BofA employs 217000 people, and just like in any other large bank and even general population, a certain percentage of them have been, are, and will be thieves and criminals, including part of the management, who will take opportunities to defraud their customers and their company. Kind of like how Walmart employees stealing merchandise or Chipotle employees coming into work infected and poisoning customers, that happened. The goal here is not to destroy every faulty organization, but to try to identify the responsible, fine and correct those crimes.
