Thanks to the upholding of a federal law, sex offenders like John Albert Gardner III will most likely never be released from prison to repeat their crimes. (Last Friday, Gardner was sentenced to life in prison without possibility of parole for murdering two teenage girls after serving time for another sexual assault of a minor.)

Yesterday, the Supreme Court ruled that federal officials can keep "sexually dangerous" inmates incarcerated indefinitely. Justice Stephen Breyer, who wrote the majority opinion, stated that sex offenders with "serious difficulty in refraining from sexually violent conduct or child molestation" can be held in prison even after they have served out their initial sentence.

Some say this policy should be taken a step further, and that if an offender is found to be likely to repeat his offense, he could opt for voluntary castration -- and be released. According to Susan Feinstein in her article "Castration Works," "Chemical castration decreases the occurrence of repeat offenses from 75 percent to 2 percent."

Do you think sexual offenders should be given the choice of either life in prison or castration?
