OK....first thing: Is this really illegal? If so, who is really in trouble, Rush, or the physician?
It's the Customs officials and/or the Palm Beach County Sheriff's office that ought to be in trouble here, for making this public. It's not clear that Rush committed any crime, nor has he been charged with committing any crime, and yet he's being put through public embarrassment with the story of what pills he's taking being broadcast around the globe.
Shouldn't both Customs officials and the Palm Beach County Sheriff's office have more pressing matters to attend to these days???? And why does anybody need a prescription for this stuff anyway? It's not an addictive narcotic, and has nowhere near the potential for harm that acetaminophen (e.g. Tylenol) has -- the latter being the leading cause of acute liver failure in the U.S.
Viagra and it's foreign counterpart, Kamagra, are easily purchased by anyone without a prescription.
If this is all they can find to worry about with Rush, they are sure proving they really were in a witch hunt.
