WASHINGTON — Homeland security officials improperly gathered intelligence on the Nation of Islam, a black Muslim group, but government rules were “unintentionally and inadvertently violated” and only publicly available information was collected, according to documents made public Wednesday.
One official wrote, “the organization despite its highly volatile and extreme rhetoric has neither advocated violence nor engaged in violence” and should not have been the subject of intelligence gathering. The documents were released Wednesday as part of a Freedom of Information lawsuit, but the DHS report itself was not released nor were any examples of what the analysts considered extreme rhetoric.
