The Supreme Court is declining to take the case of a Pennsylvania rapper who was convicted of threatening police officers in one of his songs.

The high court declined on Monday to take the case of Jamal Knox, known as Mayhem Mal. In 2012, he and rapper Rashee Beasley were arrested by Pittsburgh police on gun and drug charges. A song they later wrote about the arrest contains phrases including “Let’s kill these cops cuz they don’t do us no good.”

Both were charged with terroristic threats and other crimes.

Knox argued that the song was protected by the First Amendment, but he was ultimately convicted and sentenced to one to three years in prison. Pennsylvania’s highest court upheld his convictions.
