This story looks at the case of Dr. William Dando, who was licensed to practice in Maryland even though he had been convicted of raping a woman years earlier in Florida. Maryland is one of 16 states that do not make a criminal background check a condition of licensure. Until the Dando case, the Maryland State Medical Society had opposed a mandatory criminal background check for license applicants, illustrating how physicians can thwart regulators who want to hold them accountable for their behavior.
