V- Is there a pedofile gene?

I was just reading tonight a book about 'killers, stalkers, and rapists' called "Obssession," by John Douglas and Mark Olshaker who have written this book to inform and give people ideas about crime prevention. Every time I see a news story about child molestation, abduction, murder I don't think there can be too many discussions of what can be done to stop crime. This book talks about 'how to fight back.' So I am going to continue to do these videos moving from the pedofile to domestic violence as we have what is to me an astronomical number of murders of women by men in relationships with them. Oftentimes the boyfriend a mother might engage to watch her children when she goes out, either to work or some other necessary errand has been guilty of a crime against the children, even resulting in their deaths, but also may be holding her captive, too, with extreme violence. This has been a very common type of murder here in Phoenix. For every case we see in the news, I think there are thousands of children and women being abused by the stronger male partner going silent about it, with hardly anyone to turn to for help, until it is too late.
