First off I think it was more than just an investigation.
In courts if you are found guilty whether you are indegent or not, you have to pay court costs.
Now if what I read on a posting is correct, Rush plead Nolo Contendere. Here is a snippet about Nolo Contendere.
"Generally, defendants pleading nolo contendere will be found guilty of the offense by the court, as there rarely is (or can be, even) an effective defense without contesting the charge at hand. Furthermore, a nolo plea generally has the same effect as a plea or verdict of guilty for purposes of sentencing, and, depending upon the jurisdiction, may have the same effect as a conviction for the purposes of civil disabilities (such as loss of a driver's license or the right to own a firearm) or use as an aggravating factor if the defendants are later convicted of another offense."
Get your facts straight.
"Mr. Limbaugh and I have maintained from the start that there was no doctor shopping, and we continue to hold this position. Accordingly, we filed today with the Court a plea of 'Not Guilty' to the charge filed by the State." ~ Roy Black
