Obviously, there is an issue when it comes to charging children with crimes, particularly since it’s an either/or situation. I do think that it’s quite possible that, say, an 7yo may not fully understand full consequences of his actions, maybe not really realizing that his attempt to really hurt someone might result in death or that death really was a permanent sort of thing, but I’d have a very hard time believing a 17yo didn’t. A 12yo is right in the middle, and not being a specialist in cognitive development, muchless knowing the exact development of those kids, I don’t know where they may lie on the continuum.
Personally, I’ve known someone who commited a felony as a minor. He was 16 at the time and stabbed someone claiming it was an accident of sorts. As I came to found out later, he had not onlt intended to stab him, but had intended to kill him, had lied about how it happened on the stand, and got another witness to lie about what he saw as well. He got convicted of a lesser crime, got out after a short time, and ended up attempting to kill at least two more people before he finally got a long term sentence, as the latter one was very severely injured. IMO, if he had gotten charged as an adult and gotten the proper psychological evaluation he needed, considering the signs of a psychopath were all there, maybe he would have gotten a more appropriate sentence and the later crimes might have been prevented.
Regardless, I don’t see why it’s inherently wrong to charge a kid as an adult, maybe we can argue that a 12yo doesn’t fully grasp the consequences of murder, okay fine, but surely those kids at least understand the idea of severely injuring and possibly disabling someone. So, in that regard, maybe they’re legally incapable of murder, but ought to be at least legally capable of assault with a deadly weapon, maiming, malicious wounding, or whatever other laws DO cover the intentions.
That is, my opinion would be that for someone over 18, it’s sort of a given that they understand these things, and it’s only a defense that they don’t if they have some sort of mental development problems. So why not just say if they’re under 18, the prosecution just has the extra burden of proving they are mentally developed enough to understand their action and to charge them with the appropriate crime based on that. And then, for those convicted of a crime under age, there’s an additional burden of doing mental health treatments and evaluations and possibly having that affect the sentence.
Either way, it seems patently ridiculous to me to never charge anyone under 18 as an adult, especially if we can show they fully understand their actions and are likely to repeat them, and just let them out of juvenile prison sometime between 18-21 just to potentially do the same or worse. Admittedly, my personal anecdote probably isn’t typical, but there are kids out there like that, and I suspect that a kid capable of doing a heinous crime is probably a lot more likely to be like him than not.
