following two years of investigations, Assistant State Attorney James L. Martz requested that the court set aside Limbaugh's doctor–patient confidentiality rights and allow the state to question his physicians. Limbaugh's attorney opposed the prosecutor's efforts to interview his doctors on the basis of patient privacy rights, and argued that the prosecutor had violated Limbaugh's Fourth Amendment rights by illegally seizing his medical records. The American Civil Liberties Union issued a statement in agreement and filed an amicus curiae brief in support of Limbaugh. On December 12, 2005, Judge David F. Crow delivered a ruling prohibiting the State of Florida from questioning Limbaugh's physicians about "the medical condition of the patient and any information disclosed to the health care practitioner by the patient in the course of the care and treatment of the patient." On April 28, 2006, a warrant was issued for his arrest on the charge of doctor shopping. According to Teri Barbera, spokeswoman for the sheriff, during his arrest, Limbaugh was booked, photographed, and fingerprinted, but not handcuffed. He was then released after about an hour on $3,000 bail. After his surrender, he filed a "not guilty" plea to the charge. Prosecutors explained that the charges were brought after they discovered he received about 2,000 painkillers, prescribed by four doctors in six months, at a pharmacy near his Palm Beach mansion. In 2009, after three years of prolonged discussion regarding a settlement, prosecutors agreed to drop the charge if Limbaugh paid $30,000 to defray the cost of the investigation, completed an 18-month therapy regimen with his physician, submitted to random drug testing, and gave up his right to own a firearm for eighteen months. Limbaugh agreed to the settlement, though he continued to maintain his innocence of doctor shopping and asserted that the state's offer resulted from a lack of evidence supporting the charge. Before his addiction became known, Limbaugh had condemned illegal drug use on his television program, stating that "Drug use, some might say, is destroying this country... And so if people are violating the law by doing drugs, they ought to be accused and they ought to be convicted and they ought to be sent up." Viagra incident In June 2006, Limbaugh was detained by drug enforcement agents at Palm Beach International Airport. Customs officials confiscated Viagra from Limbaugh's luggage as he was returning from the Dominican Republic. The prescription was not in Limbaugh's name.
