Nursing scandal.
Two examples given by Former DPP Nazir Afzal on BBC Breakfast were...
A rape case that took 7 years before the male nurse was found guilty and sacked.
A case where a male nurse was caught viewing child porn images on his smartphone. Category one images which are the worst kind. The NMC decided there was no case to answer as it was his private life, not work related. He is still working in a hospital somewhere.
