The biggest threats to children are the sickos that are allowed to live in the home with the children - the ones their debased mothers drag home from the bars or assorted drug orgies.
They don't murder the children and get national attention. They just molest them, beat them, and other horrifying things.
That's where children are most at danger.
Good idea! Single women with children should not be allowed to have men spend the night while their children are in the home. That ought to be fun to enforce! /sarcasm
