How long are regulators allowed to persist with their foolishness?

Sir I refer to so many news, about when a downgrading of credit ratings cause much havoc, like for instance Nicole Bullock´s report on April 19 “Muni bond risks grow after S&P’s DeKalb cut”.

It is high time to ask our regulators some basic questions like when they believe banks incur in the risk of lending, when they make a loan or when the borrower is down-rated. Of course, when they make the loan!

And so I ask how long should we allow the regulators to insist on a foolish system with retroactive corrections, based on credit ratings, and which makes the difficulties encountered with a client that turned out to be worse than he was originally rated even more difficult, and not a system of upfront capital requirements independent of ratings.
