"But the most important thing is, Enron did not cause the California crisis"

This quote by Kenneth Lay is referring to the California energy crisis of 2000-2001. The crisis was caused by a combination of market control, deregulation, and other aspects. Lay is stating that Enron, the energy company he was the CEO of, was not the reason for the crisis. He is likely attempting to distance Enron from the crisis, as the company was accused of manipulating the energy market in California. Lay is most likely trying to protect the credibility of Enron, as the business was currently facing analysis for its questionable company practices. This quote is an effort to deflect blame far from Enron and onto other aspects. Lay is trying to secure the track record of Enron, and this quote is an example of that.
