PHILADELPHIA -- Meek Mill crouched on the court before a Philadelphia 76ers game and grabbed the hand of a shy 7-year-old boy for a quiet chat before more kids swarmed the rapper for a photo.His message for the boy — and for all the Philly-area children affected by the criminal justice system who were invited to play basketball with Meek Mill — was one of compassion.“I am one of those kids, so I know what it means to be in those types of situations,” Mill said Wednesday.
