If the accounting auditors are doing their job then the bank managers don't get to cook the books. The accounting rules are set by the accounting industry. If the financial statements don't reflect what's happening, it's the accountants fault. So, it's incorrect to imply that bankers are doing something nefarious. At this point no one has suggested an Enron or FTX type scandal.
What's more likely is just the incompetence with liquidity management, incompetence with the crisis handling.
