Hey, it wasn't my idea; a commenter raised the question in response to a recent blog post in which I argued that bad parenting is the number-one cause of failing students and failing schools and, consequently, the best point of intervention for public education reform. But it is an intriguing idea. Let's look at this realistically. Really bad parenting is already a crime; it's called child abuse. So it's not an issue of whether to make bad parenting a crime, but the threshold at which bad parenting becomes a crime.
