Rоn wаs а fаmоus businessman and wealthy real estate investоr who was so successful and well-known that he sometimes appeared as a guest “shark” on Shark Tank. His wife Betty was planning to leave him, because she was convinced he was cheating on her with several other women.  To gain an advantage in the divorce, Betty installed hidden home security cameras in secret locations in the living room, bedroom, and kitchen of their shared home. While Betty was not at home, Ron invited his mistress Marilyn over to the home, where the cameras caught him on videotape engaging in his extramarital affair.  The tapes also captured the housecleaner, Sarah, cleaning the house in a bikini top and shorts. During the divorce proceedings, Betty introduced the tapes as evidence to help her gain an advantage.  While testifying during the divorce proceedings, Betty became angry during Ron’s attorney’s questioning and she shouted out, “He’s not only a cheat in his marriage, he’s also a cheat on his finances!  He’s falsified his business tax returns and stolen money from his dying aunt for the past 5 years!”  Ron had done no such thing, and Betty knew it, but she didn’t care.  She was going to take him down.  Betty was granted her divorce. After the divorce was granted, Betty released snippets of the footage to several news outlets, and repeated her accusation that Ron had falsified his business tax returns and stolen money from his dying aunt.  The major news outlets aired stills from the footage, including images of Marilyn and images of Sarah.  Betty then released the full video footage to a single YouTube channel, which published the footage, racking up millions of views (and thousands of dollars in profits for the content creator).
