without mentioning names, there's nothing they can really do. They dont really care i think. The only reason that they dont/wont use it is because of the entire face that rap music has... random violent threats. The thing is, majority of these are just talk, so i doubt any specific one would be taken seriously. Even look at the lack of reaction to 50s song "Heat" in which he says "somethin somethin i give a fuck if i get caught? the DA can play this mother fuckin tape in court. i'll kill you, i aint playin, you hear what im sayin homie i aint playin".
