This is true. Kids' constitutional rights are also a mess; for a long time, they were relegated to the juvenile justice system which was able to do essentially anything it wanted to them in the guise of being a "kind and just parent." This culminated in the Supreme Court case In Re Gault.
In Re Gault was about a 15 year old kid who allegedly did a stupid crank phone call to a neighbor. (I don't think it was ever proven that it was actually him; he said it was his friend and he kicked his friend out after the phone call was made.) The sheriff took him into custody, his parents were not informed, and he was kept at the local jail. After that, the judge in the case decided that he needed to go to the state reform school until he was twenty-one (21) god damn years old.
Important to note that these reform schools were unregulated rarely inspected abuse factories. As with pretty much any time you hide away children and put adults in charge of them who can do anything they want, the children were often directly physically and sexually abused, used for forced labor, locked in solitary confinement, deprived of education, forced into religious conversion... What happened to these kids is very similar to the unceasing horror and violence done to Native Americans in residential schools, complete with unmarked graves, and just like with the indigenous peoples, authorities patted themselves on the back for taking care of the problem.
Gault, in this process, was not:
Told what specific crime he was charged with (the judge tried to backtrack and say it was a different one later)
Given a transcript or the ability to make a transcript of the proceedings
Allowed to appeal the decision.
His parents brought it to the state Supreme Court anyway on a habeas corpus petition, which the Court referred back to the original judge to decide. When the original judge decided that he'd been right after all, they brought it back to the state Supreme Court, which said that all the problems seemed cleared up now.
The United States Supreme Court reversed 8-1 (THERE WAS A DISSENT!!!!) and gave kids, at that point, in the year of our lord 1967, the right to know what charges they had, the right to confront their accusers, and the right to have an attorney.
I joke-not-joke that the only right that kids have in the United States is the right to me. Because they do get an attorney when they get dragged into court! They get fuck-all else.
