The thing is, these kids need to learn how to react to reasonable authority. When children this age, with at least average intelligence can't be convinced to behave respectfully in a court of law, someone outside the parents needs to take control and teach them this skill. I've been in juvenile court and watched kids who seem to be of average intelligence be declared "incorrigible" (meaning, in Texas, the parents can no longer be fined for the kid's outrageous behavior) because the kids couldn't shut their mouths. SHUT YOUR MOUTH. That's not a difficult concept. Look the judge in the eye, say yes ma'am or yes sir, and otherwise shut your mouth. You can't succeed in life if you can't grasp that basic social skill. This could have been done more gently than jailing them - maybe - but it's time for someone else other than the parents to step in and teach these kids a little intelligence.
