Racist Site: Lynch Jena Six

A white racist website urges a lynching of the Jena Six. The above article (and this) reports that the site "essentially called for their lynching," while this article has the site explicitly proclaiming "Lynch the Jena 6." Both articles agree that the site lists phone numbers and addresses for some of the Jena Sixers "in case anybody wants to deliver justice." FBI agents are are deciding if the site violates any federal crimes. It seems to me that either it does, or laws ought to criminalize calls for murder, especially murder that qualifies as terrorism, as is the case here.
