Most of the domestic groups that we have to pay attention to here are white supremacist groups. They're anti-government and in most cases anti-abortion. They are usually survivalist type in nature, identity orientated. If you recall, Buford Furrow came to Los Angeles in, I believe it was 1999. When he went to three different Jewish institutions, museums, and then wound up shooting people at a children's community center, then shooting a fellow penal postal worker later on. Matthew Hale who's the Pontifex Maximus of the World Church of the Creator out of Illinois and Ben Smith who went on a shooting spree in three different cities where he killed a number of African Americans and Jews and Asians that day. Those groups are groups that claim to be extremely anti-government and Christian identity oriented.
