The difference is that Hope took a no contest on drug trafficking not drug possession. Drug trafficking carries mandatory minimums, 15 years in her case for the drug and the amount she was charged with.
Ron was charged with possession (not trafficking) in 2005 and was deemed to be eligible for treatment.
Ron may get around this set of charges like he has in the past, get them dropped, beat them at trial, cut a plea where he cops to a lesser charge, but he cannot be convicted of trafficking and get a slap on the wrist. He is too old for the youthful offenders program and I *believe* deferred prosecution for completion of treatment is a one time use of your get out of jail free card.
