My understanding is that the 1st amendment applies up to the point where a person makes a specific, realistic threat. This hardly seems like a realistic threat -- it is a stretch to even call these lyrics a threat -- and I am having trouble seeing where he made reference to any specific target for this supposed attack. I see typical outrageous rap lyrics here, nothing worth taking serious as either a threat or a music.
