So what if it was struck by debris? Most of Manhattan had debris scattered everywhere, and people were choking on the other side of the island. Am I supposed to care about what you think qualifies as 'acceptable' to occupy the radius of ground zero? It's their private property and they can do whatever they want with it. To suggest they are gloating about the 9/11 attacks is absurd and there is no proof other than paranoid rantings of pundits and their dimwitted followers.
