We have a good example with Mia Farrow’s brother: he has been sentenced to 10 years in prison for sexually abusing two boys in his Maryland neighborhood.
Mia Farrow favored her biological children: three Asian children are dead, two by suicide. She betrayed her friend Dory Previn, cheated Woody Allen with Frank Sinatra, brainwashed and coached Dylan Farrow, etc.
Despite Fact 1, the alleged abuse took place in a house full of people hostile to Woody Allen. They had also been expressly ordered to watch him, and never to leave him alone with Dylan.
