A police officer directly witnessed the crime, OR

Someone is willing to come forward with sworn testimony that is reviewed by a judge and deemed to be enough to issue a warrant for arrest.

YES! YES! Right now whoever makes an accusation against you for harming your child is kept secret. In any criminal case, you are allowed to know who accused you. But not when they rip your family apart and kidnap your child.

A good friend of mine told me how her child was stolen by the system (put in foster care) because someone accused her husband of sexually abusing the girl. They never knew who made the claim based on what evidence, so they could not properly counter the claim.
When they finally got to have it all heard out in court, a court clerk made a mistake and instead of crossing out the accusers name, she crossed out the Social Workers name. That is when my friend found out that the accuser was a neighbour that had been trying to get her to sleep with him. She kept saying no, and she made it clear that she was married and would never cheat on her husband. So this horrible man decided to accuse her husband of sexual abuse of a child just to get the husband out of the picture.

It is utterly disgusting. On top of that, the community turned against her husband, and her for staying married to him, because they believed that he was a sexual deviant.

They did eventually get her daughter back, and the judge told off the social workers for how horribly they handled the case. They would never have gotten the daughter back if the judge had believed the charges.
