Meek Mill has gone public with his justice protest.
RadarOnline.com can reveal that rapper bought billboards all along Philadelphia's Interstate 95 from the airport to the city center.
They read: STAND WITH MEEK MILL: 6/18 12PM
It is understood he is planning a protest in the city on that date.
The rapper managed to secure his release from prison thanks to an order from the Pennsylvania Supreme Court, ending his controversial five-month incarceration.
The Supreme Court ordered that Mill be released on unsecured bail, meaning he must show up for future court appearances or risk facing imprisonment again for failure to appear.
Mill and his supporters want him to be totally exonerated from a previous conviction on gun and drug offenses.
