Emblematic of this relationship was a panel held at a 1999 CCC conference that featured Spencer and the leaders of three other well-known anti-immigration organizations: Wayne Lutton of The Social Contract Press; John Vinson of the American Immigration Control Foundation; and Virginia Abernethy of Population-Environment Balance. Not long after, Abernethy and Lutton joined the editorial advisory board of Citizens Informer, the racist tabloid published by the CCC. Since then, the publication and its parent group have shifted their attention more and more to the supposed evils of non-white immigration.
Our investigation also included a visit by Beirich to the border to look into charges of vigilantism against the Barnetts and others. Documentation provided by the Mexican consul's office showed that detentions were frequent and often involved force. And the number of self-described immigrant-catchers was growing. In 2000, the armed outfit Ranch Rescue, which the Center sued in 2003 for violating the rights of seven immigrants, began patrolling ranches, first the Barnetts', and then those of others. According to its publicity materials, Ranch Rescue was repairing fences, but the Report investigation found that the group's activities were more paramilitary in nature. And e-mails later secured by the Center made clear that the leader of the group, Jack Foote, showed substantial racial animus towards Mexicans. This research ultimately led to our first major anti-immigration story, "Blood on the Border," published in spring 2001 http://www.splcenter.org/intel/intelreport/article.jsp?aid=230 >. Our research also led us to list as hate groups three organizations: American Patrol, American Immigration Control Foundation, and The Social Contract Press. The following year, Coe's California Coalition for Immigration Reform would also be added to the Center's hate group list.
