To cite another example, take the case of the notorious 2001 Enron scandal that led to the bankruptcy of the Enron Corporation. Members of the executive board were indicted for their illegal and unethical actions. CEO Kenneth Lay was one of the people indicted. Lay insisted that Enron's collapse was due to a conspiracy waged by short sellers, rogue executives, and the news media — implying that while he could be held accountable as the CEO and leader of the organization, he was not in any way responsible for the fraud in the company. However, a jury found Lay guilty on six counts of conspiracy and fraud, making the CEO responsible as well as accountable for the downfall of the company.
What did CEO Kenneth Lay try to say by that? Did he imply that "he can express or explain what/how happened now but it was not his idea/ he was not not the one who organized the bribe" ?
