A helluva lot. As reported in The Brisbane Times:
Court documents reveal the GP [general practitioner], known only as DAP, began having sex with patients as early as 1987.
He was twice suspended from practicing in 1996 and 2001.
He … faced disciplinary action after admitting to maintaining sexual relationships with at least eight female patients, including the daughter of an elderly woman.
The Brisbane doctor, who cannot be named to protect the identity of his victims, was twice jailed in 2005 for repeatedly sexually abusing his 10 and 11 year-old daughters.
His own daughters too! And after all that, the Health Practitioner’s Tribunal still would not yank his license. Instead, they suspended him for 5 years, concluding that his epilepsy affected his behavior! At long last, Dr. DAP’s rein of terror is over. The Brisbane Supreme Court of Appeal overturned the Tribunal’s suspension and banned this serial sexual predator from ever practicing medicine again. Here’s the source. (And it happens in the U.S. too.)
