There were massive psychiatric facility shutdowns here in the US in the '80s and '90s and the beds that still exist are needed by the delusional schizophrenic and severe bipolar patients, those that psychiatry can have a positive effect on. Psychiatric treatment has minimal effect on pedophiles. It would be cruel and counterproductive to waste psychiatric beds on people who can't be significantly helped.
Precisely. The urge is involuntary, the choice to act it out on a helpless child is just that, a choice.
Medication and/or therapy can usually be a mandated part of a prison sentence if a court appointed psychiatrist recommends it and the judge agrees.
The only thing that has shown any significant effect in controlling pedophilic urges is castration, either surgical or chemical. There is significant reluctance in many states to use it on sex offenders for a myriad of reasons: lawsuits from the ACLU alleging that it's cruel and unusual punishment, possible lawsuits for negative side effects, concerns over informed consent and possible permanent physical damage, and the high cost of the drugs and monitoring. While surgical castration is far more effective as an isolated permanent treatment, it's obviously out of the question. Only chemical castration could ever be widely accepted and it's less effective, especially if the offender isn't receiving other forms of treatment at the same time. In light of all of this, for many states, prison for pedophilic rapists is a more effective way to keep their children safe.
You're assuming that pedophiles can be cured psychiatrically. There is no evidence for this. At best, psychiatric medication and therapy in conjunction with chemical castration can reduce recidivism significantly but conventional psychiatric treatment in the absence of drugs to tame the libido are only marginally helpful. If castration is off the table, as it is in many states, keeping them in prison and away from children is the only viable option.
Very true. In general, you're only legally insane if you are so delusional that you have no understanding of right and wrong and no appreciation for the consequences of your actions.
In Delaware fourth degree class C felony rape is basically the statutory rape law. It's meant to be used on adults who have penetrative sex with post-pubescent teenagers who are below the age of consent. It was never meant to be used on pedophiles who rape someone under the age of 12, they are supposed to be charged with first degree class A felony rape. The fourth degree charge was the result of a guilty-plea deal with the prosecutor. Despite this, the statute does allow the judge to issue a maximum 15 year prison term for egregious cases and the judge completely ignored that.
