I would have to agree with Greg in how easy it is to obtain bomb instructions. Even though the person trying to make the bomb may fail at the first attempt there is still the chance that they could succeed. Parents in particular need to keep in touch with their children. It should not matter how much money a family has that has nothing to do with the quality of child you will raise. Nor does it matter if the parents are divorced.
Children can still have a good childhood even with a broken family.
It really depends on how the parents treat the kids, do they pay attention, ask them questions. That does not mean that they should snoop in their child's room just stay on top of things, if something is a little out of the ordinary check it out.
