Bell, who had a nearly spotless disciplinary history,recorded the song away from school during winter break, and he never played it or performed it on campus.

Nevertheless, school officials -- who, it should be noted, did not investigate or deny the allegations against the coaches -- eventually learned about the song and suspended Bell, forcing him to attend an 'alternative' school for six weeks. During the disciplinary process, administrators never notified police. They never bothered to search Bell's locker.

In other words, nobody at the school appeared to believe that the song was a threat. Even one of the coaches identified in the song said he thought it was 'just a rap.'

And yet after Bell appealed his punishment, arguing that his song was being misrepresented, the School Board upheld his suspension on the grounds that he had 'threatened, harassed, and intimidated' school employees. The School Board's misguided decision was later upheld by the Fifth Circuit Court of Appeals in a divided opinion.

Now if the U.S. Supreme Court agrees to hear the case, it has the chance to get things right.

As we argued in an amicus brief filed on Bell's behalf -- a brief that has drawn the support of numerous scholars and well-known rap artists alike -- Bell wasn't being punished for making threats against school employees, even if that was the school's justification. Instead, he was being punished for using the wrong art form, rap music, as his voice of protest.

Rap, which grew out of black and Latino communities that were facing urban decay at its worst, has been contentious, sometimes polarizing, for as long as it has existed. No doubt, this is in large part because of rappers' willingness to confront institutions of power and openly defy social conventions with language that is provocative, even offensive, to some.

Bell certainly uses this type of language in his song, at times directing it at specific individuals, but in doing so he is following a long line of platinum-selling rappers -- including Ice Cube, Eminem, Nas and Jay Z -- who have built careers and made millions doing the same thing.

Throughout those careers, none of their fans ever believed that Ice Cube would kill former Los Angeles Police Chief Daryl Gates, that Eminem would kill his wife, Kim, or that Nas and Jay Z would kill each other -- all claims the rappers made in their songs.

Likewise, we don't assume that Quentin Tarantino, Stephen King or Johnny Cash carry out the (sometimes extreme) violence depicted in their art -- because we acknowledge it as art.

But as we have noted before, rap is often denied that respect, particularly in the criminal justice system, where amateur rappers, almost always young men of color who lack the name recognition (and bank accounts) of their professional counterparts, are routinely prosecuted for their music, either because people believe that rap should be read literally or because they just don't like it.

The administrators at Itawamba Agricultural High School just didn't like it. Although they maintain that the song was 'disruptive and threatening,' none of them acted as though the song were a real threat; even the Fifth Circuit denied that it rose to the level a 'true threat' (a category of speech not protected by the First Amendment).

Instead, what's clear is that people were offended by Bell's brazen attempt to stand up for his fellow students. During Bell's hearing before the school's Disciplinary Committee, one committee member made the school's motivations clear, telling Bell, 'Censor that stuff. Don't put all those bad words in it. ... The bad words ain't making it better.'

This isn't the first time officials at Itawamba Agricultural High School have tried to silence and marginalize students they find offensive.

In 2010, the school made headlines for canceling a prom rather than allowing two lesbian students to attend as a couple. One of the young women, Constance McMillen, took the school to court to defend her First Amendment rights, and she won.

Now it's Taylor Bell's turn.
