On perhaps one of the worst crimes perpetrated in Facebook, a Pennsylvania father was arrested for allegedly asking his teendaughter for sex over Facebook. John Forehand, 39, referred to himself as "Bad Daddy" in the online correspondence with his13 year-old daughter, in which he openly propositioned her and made explicit sexual suggestions. Forehand told his daughter he hadbeen having"inappropriate" dreams about her, and wrote toher, "I'll take very good care of my little girl."The girl told her mother about the inappropriate Facebook messages, and she then alerted the police. The police captured Forehand by tricking him into coming to what he believed would be a meeting with his daughter. How sick is that?
