Kill Me a Judicial System?

I find that the two-year jail sentence Antavio Johnson was served with is wrong. He created a song, which, in his own right, is a piece of art. A man was arrested for creating. Since when does any person get arrested for creating anything? Can you imagine being held in a prison cell for simply painting a picture of a police officer being shot? For me, this is unimaginble. I don't find this situation to be one of the freedom of speech more than it is about the freedom of creatism. Whether it be a scultpure, drawing, song, or even a poem, everything made is in the realm of creativity, where everyone's feelings can be opinionated without punishment. Now, if one was to make a plastic explosive, this does not fall under the same catagory. I'm talking about something that can be used for an everyday component of the art medium. I don't think it matters if he posted it on Myspace or sold a million CD's - he shouldn't have been taken in for expressing and showing off his work. I believe that the only problem here is the perspective of different people, the perhaps ignorant take on other's thoughts, and the refusal to accept other's opinions. Using the situation as an example, the judicial system as a whole couldn't see the point of view that such people as Johnson and Ice Cube had. These rappers were trying to be punished for a deeper meaning and argument that the system could not or refused to have an understanding for. I think that everyone, especially in power, should try and have a more open look at other's ideas and beliefs, even if not in agreeance with them, so for Johnson to be considered "right" or "wrong" for his art is the real crime to me.
