I have lived in almost all of them as a traveling nurse. My travels,took me to other places too, such as Africa, Europe, the USVI, Hawaii, Alaska, and more. And yes, I meant all.
I realize my example is extreme. No sane judge or prosecutor would put the 8 year old on trial. However, the elements of sexual predation are present still as the act would fall into the abnormal behavior since the other child was not mutually engaged in what would otherwise be age appropriate behavior. But all means all. I find this an important question though and I hope you do not just cast it aside.
When dealing with minors the situation is especially tricky. There are court cases wherein some would think no punishment is severe enough. But there are many minors who while engaging in what is demonstrative of aspects of sexual predation skirt the lines.
I understand the whole let's get tough on predators angle, but at a certain point we are abusing laws and unnecessarily destroying lives. I am not suggesting in the duggar case he did not deserve severe punishment, I am suggesting that there are cases where we take a law and run a direction that is not necessary or helpful.
An example of this would be prosecution under child pornography laws of teens and preteens for sending pics to each other of themselves. Now this is not an overly prevalent problem in the justice system but it has happened. Some people want to stick to the very letter of the law even when it defies common sense. So, we need to be articulate and when we say all, we must mean all. Then we need to discuss how we deal with juvenile offenders. If we are serious about rehabilitation, prison and permanent placement on an offender list does not always fit for juvenile cases, even of sexual assault. While there are cases where I would support branding a kid for life and sending them to prison, there are also cases where such would not fit any conceivable notion of justice.
