I haven't said anything on this subject prior to now, but I find it strange that the parents even still have custody of their other two children.

If they had made a habit of leaving three children under the age of three alone in their own house for more than an hour at a time and one of them died in a fire while the parents were gone, would the remaining two children have been left in their custody?

What if they had left them alone, and the oldest of the three had managed to find and consume a fatal quantity of some kind of medicine? Or if one of the younger children had choked to death on a button that came off of a piece of clothing and rolled under a chair where no one had noticed it? Or if one of them had pulled a lamp down on his or herself, causing the bulb to break and was then electrocuted after putting a finger where the bulb had been?

How is it that the kind of neglect that resulted in this abduction hasn't been considered grounds for the parents losing custody of the remaining children?
