Rappers including Killer Mike, Chance the Rapper, 21 Savage, and\u00a0Meek Mill contributed to an amicus brief submitted to the Supreme Court today on behalf of\u00a0Pittsburgh artist Jamal Knox, who was sentenced in 2014 to two years in prison on\u00a0criminal charges based on lyrics in\u00a0his\u00a0song "Fuck the Police." Members of The Lox and 2 Live Crew, Jay-Z's company Roc Nation, former Spin editor Alan Light, music\u00a0attorney Dina LaPolt, and 12 scholars, among others, were also named\u00a0as filing parties.\u00a0The brief\u00a0offers a "primer on rap music and hip hop" and argues\u00a0that\u00a0rap lyrics\u00a0do not legally constitute a "true treat of violence." Knox recorded "Fuck the Police" after being arrested in 2012\u00a0on gun and drug charges, and he was subsequently charged on additional counts of\u00a0terroristic threats and witness intimidation. Prosecutors submitted the song's printed lyrics in court and\u00a0police officers testified about their reactions to the\u00a0track. Knox was convicted on all counts and\u00a0the Pennsylvania Supreme Court upheld the ruling on appeal. He has since\u00a0appealed the\u00a0decision to the Supreme Court, which\u00a0advocates hope will rule definitively against\u00a0the common practice of citing rap lyrics as criminal evidence. The brief declares\u00a0that\u00a0Knox's song "is\u00a0a work of poetry," adding, "It is told from the perspective of two invented characters in the style of rap music, which is (in)famous for its exaggerated, sometimes violent rhetoric, and which uses language in a variety of complex ways. It is not intended to be taken literally, something that a reasonable listener with even a casual knowledge of rap would understand." Killer Mike, whose own\u00a02012\u00a0song "Don't Die" is quoted in the brief, told\u00a0The New York Times that the use of rap lyrics\u00a0in court is\u00a0"racial profiling," and\u00a0compared the practice\u00a0to stop-and-frisk policing. "Outlaw country music is given much more poetic license than gangster rap, and I listen to both," Mike\u00a0said. "And I can tell you that the lyrics are dark and brutal when Johnny Cash describes shooting a man in Reno just to watch him die and when Ice Cube rapped about a drive-by shooting early in his career." Boosie\u00a0Badazz\u00a0and\u00a0Drakeo the Ruler\u00a0are among the more high-profile rappers whose lyrics have been used against them by prosecutors in recent years. It remains to be seen whether the brief will persuade the Supreme Court\u00a0to hear Knox's case, but either way, it's a\u00a0valuable read. You can find\u00a0the full brief here.
