A nurse would be expected to react differently than females who were not 'women of the world' if a man exposed himself on the MTR, a judge was told yesterday. Christopher Grounds, representing a company boss convicted of indecently exposing himself in the presence of a nurse, said she would see this part of the body regularly in her working life. 'Are you suggesting nurses cannot be affronted by men exposing themselves on the MTR?' asked Madam Justice Clare-Marie Beeson. Mr Grounds said: 'I am not saying she should not be affronted. I would never say that about anyone. But there are various ways of reacting. She reacted like someone who has never come across this aspect of a person's body before.' The 40-year-old woman approached the man, shouted at him and pressed the emergency button before complaining to the police. Mr Grounds said this was a 'hysterical reaction which would be highly unlikely from a lady in her position'. 'That is not to say some people, from a sheltered background, who were not women of the world and led their whole life and experience in a particular way would not react in that manner,' he said. Mr Grounds raised the issue to support his argument that in cases of indecent exposure, the victim's account should be treated with particular caution in the absence of any supporting evidence. He said it was possible the man did not realise his zip was undone and had inadvertently touched his genitals because of a pain caused by a medical condition from which he suffered. The judge ruled that supporting evidence was not needed in such cases and dismissed the appeal. Cheung Kwai-leung, 30, had been found guilty at Western Court of indecently exposing himself on an MTR train from Admiralty to Central on March 11. He was fined $2,000.
