On the Fact that the Findings from the Financial Crisis Inquiry Commission Didn't Come Out Until a Good Six Months After the Congress Passed the Dodd-Frank Act

While, yes, the findings that this commission came up with were at the very minimum incomplete (not much mention of the Fed's easy money policies, of Fannie Mae and Freddie Mac buying up hundreds of thousands of sub-prime loans, of the government's push toward reduced lending standards, of the failure of government-backed ratings agencies, etc.), would not it have been a much more prudent plan of action to determine what went wrong first and THEN try and fix it, as opposed to the other way around? I'm just asking.
