Carl Levin actually said...

Corruption was rampant at that bank. Did you believe it was rampant?

given past commitments that have not been kept that the bank has a heavy burden of proof that they mean what they say

Well, these words are the benefit of hindsight. Given what you knew then, should you not have taken enforcement action?
