The state doesn't have to provide proof; it can filibuster for as long as it wants and the parent is out of luck.
It does. At least in Belgium as far I'm aware. I don't know how crooked the average lawyer in America is but I've seen some interesting documentaries on those cases specifically targetting Jewish lawyers. Law and Justice? It always requires proof. Child abuse trials in Belgium have recieved a lot of media attention in daily newspapers every since the case of Marc Dutroux. Such cases are always taken seriously. And whenever an error occures in trials it hits front pages. Everything's documentated. Not even one couple lost its children to due abuse this year. Your words need context? If the state really can fillibuster them without proof then I want to hear your experience with this.
Or maybe this is a problem in certain Americain states but you exagerate your words and claim it is worldwide
