Boneless chicken wings did come from a chicken with bones in it,
Sure but then someone prepared the chicken and decided that the outcome can be described as boneless.
Personally, I would also expect the bones to have been removed.
You can debone chicken without turning it into pink slime.
I'd rather expect it to be made from another part of the chicken in the style of wings.
If you're distinguishing by the type of offense instead of by age, you don't have a youth justice system, you have a minor offense justice system.
Distinguishing by the severity of the offense is already part of the justice system.
Youth justice systems explicitly consider the age and maturity of the offender, not just what they did.
Also I'm not sure why a 15-year-old is a kid in one of your examples and a "kid" in the other.
This is not about tolerating behavior, it's about reforming people to become members of society instead of lifelong burdens for the justice system.
Despite the severity of his action, brandishing kids as "irredeemable" not only throws away their entire future but also burdens everyone else with keeping them contained forever.
That profits nobody.
