With the severe criminal and civil penalties the State Governments are imposing on its male citizens for child support, would part of due process be verification of paternity. They use this database for murder, why not for the life of both the child and parents. They could ID the actual father for the child's medical history and well being.
I was not looking to prove the guy in court, but to find the milkman so to speak. Some judges will stick the married man even though he is not the blood father.
