That is the symptom, not the problem. If you want to equalize those numbers, you have to fix the problem. Which is a dysfunctional culture that penalizes success. Simply letting kids get away with bad behavior in schools will only exacerbate the problem, increasing bad behavior and disrupting any learning that can actually happen.
I seriously think that liberals could benefit a lot by studying the Army problem solving method. It starts with accurately defining the root cause of the problem. If liberals knew any kind of problem solving ability at all, they would not come up with stupid ideas that are guaranteed to make the problem worse. But then, they also probably would not remain liberal.
Much of the problem can be found in the destruction of the nuclear family and our government subsidizing, endorsing and empowering single-parent (no-dad) families. So long as government is a surrogate father to children, we will continue to see children from predominately fatherless families - become lawless.
It's a shame that our politicians do what's PC rather than what's needed.
Just for informational purposes, the idea of restorative justice has worked, but only in communities with a high level of religious participation in the process. Although the proponents of restorative justice claim statistics show its viability, these have been very limited studies.
If there is not a common basis of belief, restorative justice only allows the predators to easily identify the prey which is complaining.
Liberal stupidity.
