The way I understood it, Giuliani was saying that he had spent as much time at Ground Zero as the cleanup workers in order to refute their claims that breathing the crap in the air had made them sick. Yes, he was grabbing a chunk of political capital as well. But mostly he was saying that he was there as much as they were, and he didn't get sick, so they have nothing to complain about.
This is about something much more vile than some cynical grab for the spotlight. This is about avoiding responsibility for telling lies that led innocent people to their deaths. This is about telling more lies to cover previous lies.
Talking about the time he spent with the Yankees, or talking about his other qualities, or talking about the amount of time other politicians spent at Ground Zero is actually hiding the crime. I don't think that's how we want to respond to this lie.
