Slander is not a crime, it is a civil matter whereas harassment is criminal and he mentions harassing in his statement. He also says that he is seeking legal protection which suggests that he is not talking about suing but some form of protection maybe in the form of a cease and desist.
What's interesting is that he claims most of the information said about him is untrue but he does not mention Kim once or even what sex the 'person' is. He only refers to the person as having been a close colleague and volunteer.
It's sad that he has no understanding as to why Kim felt the need to disclose the information about him. How can he have any understanding of abuse victims if this is the case?
