I believe it is just 4 of them. Mindy Kleinberg, Kristen Breitweiser, Patty Casazza and Lori Van Auken. They are known as "The Jeresy Girls". Here is a typical piece that shows their views.
The women may have a point, Coulter may have a point. All of them can say whever they want. Hey, it's still a free country and if people like or don't like what any of them say it's A-OK.
The Jersey girls were a major reason why the 9/11 Commission came into being--which was intended to discredit the Bush administration over 9/11 while shielding the Clintons from any blame (hence Gorelick's and Ben Veniste's presence on the commission).
Why, of the thosands of spouses, parents, children, or siblings bereaved by 9/11, only the opinions of those four counted is a mystery known only to the mainstream media.
