Among the organizations that actively discuss and promote such theories are Architects & Engineers for 9/11 Truth, a group that focuses on the collapse of the World Trade Center buildings; 9/11 Truth, founded in 2004; Scholars for 9/11 Truth, founded in 2005, and Scholars for 9/11 Truth & Justice, a group that split from Scholars for 9/11 Truth in 2007 and runs the online publication "Journal of 9/11 Studies"; 9/11 Citizens Watch, which was already formed in 2002; and the Hispanic Victims Group. Several of these groups have collected signatures on petitions asking for further investigation of the September 11 attacks.
