During a Dallas concert last week, Jay-Z stopped his set to speak out about rapper Meek Mill’s recent prison sentence. “He’s 30 now. He’s been on probation for 11 years. Fucking 11 years. Judge gave him two to four years because he got arrested for being on a bike and popping a fucking wheelie,” he said then. On Friday, the 47-year-old rapper wrote a New York Times op-ed to speak out further against Meek Mill’s prison sentence, and the general problems with the criminal justice system in the U.S.

“Meek was around 19 when he was convicted on charges relating to drug and gun possession, and he served an eight-month sentence,” Jay-Z began. “Now he’s 30, so he has been on probation for basically his entire adult life. For about a decade, he’s been stalked by a system that considers the slightest infraction a justification for locking him back inside.”

Last week, Philadelphia Common Pleas Judge Genece Brinkley sentenced Meek Mill to two to four years in prison for violating probation related to a 2008 gun and drug case, per Billboard. As Jay-Z noted, Meek Mill’s charges since then have been minor and have been dropped.

“In March, he was arrested after an altercation in a St. Louis airport. After video of what had actually happened was released, all charges were dropped against Meek. In August, he was arrested for popping a wheelie on a motorcycle on his video set in New York. Those charges were dismissed after he agreed to attend traffic school. Think about that. The charges were either dropped or dismissed, but the judge sent him to prison anyway.”

Meek Mill is filing a motion for his prison release. On Tuesday, Meek Mill requested “the recusal of Judge Brinkley from considering and ruling on [his sentence] and from any further adjudicatory role in this case,” recent court documents read, per Billboard.

The complaint submitted by Meek Mill’s attorney also claims that the judge ordered the rapper to confinement on November 6, despite his probation officer’s reporting his cooperative and good behavior. “Judge Brinkley has repeatedly offered inappropriate personal and professional advice to the defendant,” the attorney stated.

“What’s happening to Meek Mill is just one example of how our criminal justice system entraps and harasses hundreds of thousands of black people every day,” Jay-Z said, in his op-ed, adding that he saw examples of this kind of injustice in his Brooklyn neighborhood in the 1970s and 1980s.

“Instead of a second chance, probation ends up being a land mine, with a random misstep bringing consequences greater than the crime,” he said. “. . . Probation is a trap and we must fight for Meek and everyone else unjustly sent to prison.”
