Wrong. Recidivism rates are much higher for people who are driven by a desire for money than they are for sexual offenders. Evidence from http://bjs.ojp.usdoj.gov/content/pub/ascii/rpr94.txt
"Released prisoners with the highest rearrest rates were --
robbers (70.2%)
burglars (74.0%)
larcenists (74.6%)
motor vehicle thieves (78.8%)
possessors/sellers of
stolen property (77.4%)
possessors/sellers of
illegal weapons (70.2%).
What these high-rate offenders have in common is that they were all in prison for what are generally thought of as crimes for money. By contrast, many of those with the lowest rearrest rates -- persons convicted of homicide (40.7%), rapists (46.0%), other sexual assaulters (41.4%), other violent offenders (51.7%), and those convicted of driving under the influence (51.5%) -- were in prison for crimes not generally motivated by desire for material gain."
Sexual offenders and pedophiles are a problem, but attempting to solve it with bad data won't work.
