It makes it look like there is nothing more significant and negative to point out about Rudy.

http://en.wikipedia.org/wiki/Rudy_GiulianiCriticism for lack of preparedness before the 9/11 attacks
In September 2006, Village Voice writer Wayne Barrett and senior producer for CBSNews.com, Dan Collins, published The Grand Illusion: The Untold Story of Rudy Giuliani and 9/11,<53> one of the strongest reassessments of Giuliani's role in the events of 9/11. The book highlights his decision to locate the Office of Emergency Management headquarters (long-identified as a target for a terrorist attack) inside the World Trade Center, his focus on personal projects and turf wars rather than vital precautions for the city, and his role in communications failures (potentially related to patronage and sweetheart deals inside City Hall). Kirkus Reviews stated, "Giuliani may not have been directly responsible for all those woes, but they happened on his watch".<54>
Some family members of 9/11 victims have openly criticized Giuliani for the significant communication failures that occurred on that day. In December 2006, Sally Regenhard, mother of a late firefighter and co-founder of the Skyscraper Safety Campaign, vowed to expose the truths of Giuliani's actions on 9/11 before 2008, stating, "I can't see why any 9/11 family member who knows the truth about the failures of the Giuliani administration . . . would not be outraged."<55>
Criticism for handling of Ground Zero air quality issue
Giuliani has been subject to increased criticism for downplaying the health effects of the air in the Financial District and lower Manhattan areas in the vicinity of the Ground Zero.<56> He moved quickly to reopen Wall Street, and it was reopened on September 17. However, in the weeks after the attacks, the United States Geological Survey identified hundreds of asbestos hot spots of debris dust that remained on buildings. By the end of the month the USGS reported that the toxicity of the debris was akin to that of a household cleaner.<57> The city's health agencies, such as the Department of Environmental Protection, did not supervise or issue guidelines for the testing and cleanup of private buildings. Instead, the city left this responsibility to building owners.<57>
Firefighters, police and their unions, have criticized Giuliani over the issue of protective equipment and illnesses after the attacks.<56>An October study by the National Institute of Environmental Safety and Health said that cleanup workers lacked adequate protective gear.<58>
