If you change "indicted and tried" to "treated the same way as an average citizen does when he is accused of illegally receiving prescription drugs that he became addicted to as a result of a medical need", I'll agree with you.
One thing that's good about our justice system is its discretion. (It can also be what's bad about our justice system when that discretion is abused, of course.) My brother is a pretty tough prosecutor in Houston. He has no trouble locking up someone when that's necessary. But he also knows when to plea bargain, when to work with the defendant, when to allow for deferred adjudication, and so forth, and I respect that. And it's at the prosecutor's desk where it's important to weigh the circumstances of a crime, the likelihood of repeat offense, the danger to society, and so forth.
I expect the local authorities to give Rush the same consideration as they would to any other repentant addict. If he gets off easy, I don't want it to be because of his celebrity or his money. The same goes if he has the book thrown at him.
