There are plenty of reasons to wish Rudolph Guiliani a happy retirement.
So many that it’s not necessary to make stuff up. From Factcheck dot org:
The union representing New York City firefighters is running a misleading video blaming former Mayor Rudy Giuliani for the deaths of more than 100 firefighters at the World Trade Center on September 11, 2001.
We agree that Giuliani bears some responsibility for the widely documented failings of the fire department’s radio communications on 9/11. It is true that the effective functioning of the fire department is a major responsibility of any mayor, and Giuliani had been in office since 1994. However, the video goes too far when it implies that bad radio communication was the only reason that 121 firefighters failed to clear the North Tower of the Trade Center after the first tower collapsed. To the contrary, the 9/11 Commission stated in its final report that the technical failure of fire department radios “was not the primary cause of the many firefighter fatalities in the North Tower.”
