Though that study seems pretty good, it still leaves 2% of the convicted pedophile population open to commit, also, this study was only based on a short term study. I would be more convinced had they done a study for 10-20 years, and then give findings.. How many people stopped going in to the doctor as required, how many of those people used other drugs that could counteract the chemicals used in the chemical castration.
How many of those people fell out of contact with government officials.. basing findings on 30 people is not very accurate..
In california alone:
According to a report made to the California Legislature in July 2002 entitled California's Sex Offender Information?Megan's Law, the state had more than 93,000 registered sex offenders as of December 31, 2001. Based on past criminal convictions, slightly less than 81 percent were classified as serious offenders with 2 percent designated as high risk.
So if chemical castration was administered to all of these registered offenders, then at a fail rate of 2% that would leave approximately 1860 of those offenders possibly open to commit more sex crimes, abductions, or murders.
Lets put this on a national level, imagine we multiply that number x 50 just for shits and giggles, it won't be addurate, but it will illustrate a point.
You would have 4,650,000 sexual offenders, That will leave 93,000 sexual predators open to being able to commit a crime again based on the fail rate. That to me is not a end all solution, and is far from 100% safe.
Lets not forget also that this is for CONVICTED people.. not even the lunatics that are still on the streets able to harm kids who are untreated and not locked up.
Its pretty shocking to think that in my area alone there are 40+ sexual predators that are out on the streets... who are at risk of relapsing and commiting more crimes..
