Ferber, 458 U.S. at 764-65, 102 S.Ct. In response to Ferber, Congress passed the Child Protection Act of 1984 (CPA), which was modeled on the New York statute upheld in Ferber. In other words and phrases, Congress might not "burn the property to roast the pig." Whether that hard equilibrium has been struck in the instantaneous legislation is the situation ahead of us.
