A group of atheists filed a lawsuit Tuesday seeking to remove part of a state anti-terrorism law that requires Kentucky's Office of Homeland Security to acknowledge it can't keep the state safe without God's help.

American Atheists Inc. sued in state court over a 2002 law that stresses God's role in Kentucky's homeland security alongside the military, police agencies and health departments.

Of particular concern is a 2006 clause requiring the Office of Homeland Security to post a plaque that says the safety and security of the state" cannot be achieved apart from reliance upon almighty God" and to stress that fact through training and educational materials.
