Following a 2012 arrest in part for gun and drug charges, Knox, who performs under the moniker “Mayhem Mal,” and Rashee Beasley, who goes by “Souja Beaz,” wrote and recorded a song titled, “F*** the Police,” seen as a homage to the N.W.A. 1988 rap song “F*** tha Police.” Knox and Beasley’s song, posted on Facebook and YouTube, included the names of the two Pittsburgh officers who arrested them with lyrics like, “I’ma jam this rusty knife all in his guts and chop his feet” and “Well your shift over at three and I’m gonna f*** up where you sleep.”
