"A conservative advocacy group founded by the Rev. Pat Robertson is suing to try to block a planned Islamic community center and mosque near ground zero. The mosque proposal has become a fulcrum for balancing religious freedom and the legacy of the Sept. 11 attacks. It would be two blocks from ground zero. The American Center for Law and Justice filed a petition Wednesday challenging a city panel's decision to let developers tear down a building to make way for the mosque. City lawyers say they're confident the panel followed appropriate procedures. A spokesman for the mosque project declined to comment. Opponents say the mosque plan insults the memory of those killed by Islamic terrorists in the 2001 attacks. Supporters see it as a monument to tolerance."
