According to TMZ:
The panel declined to indict the Houston rappers Tuesday, citing insufficient evidence to convict them in the December drug bust. Paul celebrated his victory with a cigar (weed-free, we think), and told us why he was always confident his attorney would save his ass.
We broke the story ... Paul and Baby were arrested in an undercover raid while attending a weed party in Houston. They'd been booked for possession of marijuana and intent to sell, both felonies in Texas. It appeared the case was moving forward a few months ago when the artists told a judge they would test positive for THC.
Like Baby told us, they were just dabbling in dabs and pot at the shindig -- and for the grand jury that wasn't enough to warrant a trial.
