I was hoping to see Ibrahim Hooper named as a defendant..
I'd guess it is a money issue. Like Al Sharpton, Hooper is probably judgment proof. If I were litigating this issue, I'd attack CAIR under RICO. Once judgments were obtained against CAIR and its local chapters, I'd go after the individuals involved relying upon the RICO precedents established.
Regardless, bankrupting CAIR will defang Hooper and his ilk. Op-eds in the NY Times by them won't have the same effect as raising millions to support Islamoterrorists.
