@Grin Olsson:
"Simple resolution" ? How do you "require" parents to provide anything? You are already taking their kids away, why would they provide any info to you even if they have it? Secondly, siblings and extended family are generally not real excited about taking in the traumatized, psychologically damaged, sexually abused children of their mentally ill, chemically dependent or criminally prosecuted relatives for extended periods. It's not their responsibility and those are very difficult kids to deal with. Additionally, the reason that the government gets involved with families is because children are being starved, pimped out, beaten, tortured and killed by their parents and most of the folks around the US believe that is a problem that needs to be addressed.
