The Department of Homeland Security has acknowledged several new cases of improperly gathering information on US citizens and residents. On Wednesday, the Justice Department released documents showing Homeland Security officials distributed a report on the Nation of Islam to hundreds of law enforcement officials nationwide in 2007. The report was later withdrawn after a review found the analysis should never have been written because there was no evidence tying the group to acts or advocacy of violence. In another case, DHS officials circulated a “terrorism watch list” report on a Muslim conference in Georgia despite no evidence linking the gathering or its speakers to terrorist activity.
