Should Snow White have known the apple was toxic?

Sir in “Shining a light on bank´s deep hole” October 1, you write about “bad bets on risky assets”. What risky assets do you refer to? To those AAA rated securities that carried so little risk that the regulators only required the banks to hold 1.6 percent equity against them?

When Snow White was offered the apple, was she supposed to have known Queen Regulator´s helpers, the credit rating agencies, had poisoned the apple?
