Being a parent to a sex offender

CNN   Christine Smith will never forget the moment she watched her 21-year-old son being led out of a Florida courtroom in handcuffs.

"This is not happening, this is not happening, this is not happening," she recalls thinking at the time. "Take me instead."

She sobbed because there was nothing she could do. Matthew, the second of her three children, was going to prison after pleading guilty to 10 counts of possession of child pornography. A judge in Duval County sentenced him in April 2010 to 18 months in state prison and one year of probation, with the requirement that he register as a sex offender.
