Despite Madoff's guilty plea, this case is far from over. Investigators are still busy trying to figure out who else knew what he was up to, to try to hold them accountable, too. It seems inconceivable that one man could have pulled off a scam this big.
For Madoff's five thousand victims -- from large charities to retirees who'd scrimped and saved for their golden years -- today's joy will be fleeting.
