Nah they'll try every slimy trick in the book, no matter how stipidly transparent and no matter how many times they get yelled at:
Judge: "Let me remind the prosecutor that he may not ask specific questions about Mr. Rush Limbaugh."
Prosecutor: "Thank you your honor. Doctor, how many prescriptions for Oxycontin did you write for Rush Limbaugh?"
"Objection!"
Prosecutor: "Withdrawn. How many prescriptions for Oxycontin did you prescribe in 2003?" (Doctor answers.)
Prosecutor: "And how many of those prescriptions were to patients other than Rush Limbaugh?"
"Objection!"
etc.
It isn't at trial yet. After two years there still aren't any charges. What are his doctors going to say to the police if they aren't required to discuss his medical condition, and aren't required to discuss what Rush said to them?
