The Council on American Islamic Relations (CAIR), along with the American Civil Liberties Union, filed a civil rights lawsuit on Wednesday against a gun range in Oktaha that claims to be “Muslim-free.” The lawsuit was filed on behalf of U.S. Army Reservist Raja'ee Fatihah, who says he was denied service at the facility because of his faith. By displaying a sign banning Muslims, the lawsuit claims that the facility's policy violates Oklahoma's non-discrimination law as well as the Civil Rights Act of 1964, a landmark piece of federal legislation that forbids a place of business from denying service to customers based on their race, religion or national origin. On Wednesday, a sign posted on the window of the storefront of "Save Yourself Survival and Tactical Gear" says, "This privately owned business is a Muslim free establishment!!! We reserve the right to refuse service to anyone!!! Thank you!" Other signs posted say, "We support our troops," "Don't tread on my gun rights. Vote freedom first," and "No media allowed on property. No interviews. All questions can be directed to our lawyer."
