Why Have American Muslim Leaders not Issued a Fatwa against Osama bin Laden for the 9/11 Attacks?

I drew attention to the astonishing fact here that after almost five years Muslims have not yet issued a fatwa against Osama bin Laden (OBL) for the 9/11 terrorist attacks. 

The United American Committee has continued to exert pressure on American Muslim leaders to issue a fatwa condemning OBL and other terrorists by name:

Placing pressure on the leading figures of the American Islamic community, last month the United American Committee issued a challenge to all patriotic American Muslim leaders to issue an Islamic verdict, known as a fatwa, condemning Osama bin Laden and other terrorists by name. With over forty days since the issuance of the challenge, the fatwa has not been declared. The UAC has brought the challenge to several Islamic organizations such as the Council on American Islamic Relations (C.A.I.R.), as well as to many Islamic mosques nationwide.

Their latest tactic will consist of the following:

Among numerous events across the nation to commemorate 9-11, one event in the Los Angeles area will feature a mock hanging of Osama bin Laden, and will give attendees an opportunity to throw old shoes at the effigy. The hitting or throwing of shoes at a person or object is one of the greatest insults within the Islamic world. One aspect of this event which is also unique is the location; The event, organized by the United American Committee, will take place in front of the King Fahd Mosque at 10980 Washington Blvd. in Culver City, California.

The longer American Muslim leaders fail to issue a fatwa condemning prominent Muslim terrorists like Osama bin Laden the more they align themselves with the enemy in the War on Muslim Terrorists and their supporters.
