According to ProPublica:
Dozens of interviews and a review of records show that virtually every aspect of the blaze had been forecast and worried over for years. Every level of government understood the dangers and took few, if any, of the steps needed to prevent catastrophe.
This is a long read and a powerful article. ProPublica's mission statement is: "To expose abuses of power and betrayals of the public trust by government, business, and other institutions, using the moral force of investigative journalism to spur reform through the sustained spotlighting of wrongdoing."
Regardless of the conclusion you draw from this article, the simple fact is that completely relying on the government and governmental agencies to keep you safe is not worth the risk. The agencies themselves even urge everyone to prepare individually.
