The Dutch nurse Lucia de Berk spend 2 years under arrest and 6 years in prison with a life sentence for the murder of 7 babies and old people at several hospitals in the Hague (and attempted murder of 3 more). After a long public fight in which many scientists played a notable role, the conviction was reversed. The court even concluded that there had been no murders at all ... though deaths were often hastened by doctors' medical errors (mis-diagnosis, wrong medication, ... ) which till then had not even been mentioned - whether in court proceedings or in pulbic debate. Since the final verdict in 2010, there has been ... silence. Especially in the medical world: total silence.
The minister of justice apologized pulbicly, the Dutch tax-payer footed the bill. The medical community look the other way.
If you never admit mistakes, you can never learn from mistakes. It can all happen again, tomorrow.
