Yes, there are pedophiles. Yes, there are serial rapists and murders. But their numbers are few compared to less sensational crimes. Far more numerous are those, reported and not, that are committed by family members on one another, by caregivers and by people in power who demand sex in return for job security and promotions.
Offenders, basically, are a lot like you or me. They span all age groups, from juveniles to seniors, men and women (and gay and lesbian, bisexual, transgender and queer). Some are wealthy and some poor. Some are able bodied and some are not. In the U.S., the majority of sex offenders are white men. That doesn’t mean that there are none from other backgrounds and cultures. The thing they have in common: all of them make mistakes. Most of them live to regret it and “sin no more.”
An interesting statistic: those convicted of sex offenses reoffend at a lesser rate than other felons. Not only are they less likely to commit another sex crime, they are less likely to commit any crime.
