Generally, people (authorities, policemen, etc) don't get fired if they failed to prevent a disaster. They get fired if they break rules, fail to obey standard operating procedure, do not fill tick marks correctly on a paper. They work in a system, and the system has responsibility, not individual people who work for it -- unless they neglect or break rules and procedures.
