Missouri lost a Supreme Court appeal Monday over its decision to bar a Ku Klux Klan group from a highway litter cleanup program. The court's rejection, made without comment, means that the KKK chapter must be allowed into Missouri's Adopt-A-Highway program, which is designed to save money by using volunteers for garbage pickup. Volunteer groups are publicly thanked with signs along the highway acknowledging their help. Every state but Vermont has such a program. States supporting Missouri in the appeal argued that the Supreme Court needed to intervene so that states unwilling to partner with the KKK would not decide to abolish their programs. The dispute involves a half-mile stretch of Missouri 21 near Potosi, a town of fewer than 3,000 in the eastern part of the state. A KKK chapter sought permission to pick up trash along the road, but was turned down because the program is not open to groups that discriminate based on race or those that courts have said have a history of violence. Missouri lawyers had argued that a sign marking the KKK stretch of road could lead to more dumping, and could endanger highway workers mistaken for Klan members. The Klan sued and won on grounds that it had a First Amendment free speech right to participate. [more]
