place them under counselling or rehabilitation facility so they can change their ways.
They rape a little boy, how will this little boy stay? This is unforgivable and I do not believe that those involved in this criminal act will change
Counseling or rehabilitation will not help these criminals change behavior. Most likely they rape someone else again
If you think this way, you just deny facts.
"The average sexual recidivism rate found was 13.7 percent and the average overall recidivism rate was 36.9 percent, based on an average followup period of 5 to 6 years."
http://www.smart.gov/SOMAPI/sec1/ch5_recidivism.htmlIt means that 14% will rape or assault again and a bit more than a third will commit another criminal offense.
Which means that far more than half of them will not become recidivist. So they are most likely to NOT rape again.
Which doesn't mean that they should be released. You have the right to consider that the risk is still too high and that they should be killed. But do not spread false facts, Counseling or rehabilitation are not perfect but they work perfectly 63% of the time and they prevent sexual recidivism 86% of the time.
