Perhaps this is the question I'm curious about:
If you leave your child of age X alone for an afternoon and she manages to injure or kill herself, what is the minimum X such that you won't be arrested for some sort of parental negligence? What is the minimum X such that Nancy Grace won't try to destroy your life on national TV?
And, has X changed over the past 20 years?
And, in terms of arrest I don't need citation of state law, as these are the kinds of things which tend to be prosecuted with a lot of discretion. Just a general sense of how old does a kid have to be before it's "okay" to leave them alone?
