They can say that you cannot have compulsory prayer, you cannot have school-led prayer, you cannot have teacher-led prayer. I do not know whether or not the Court has said, if school starts at 8:15 in the morning, that at 9:30 Susie or Jimmy cannot say a silent prayer to themselves right in the middle of class. Maybe the Court said that; maybe it has not. But if the Court has said that, the local school board would not have the constitutional right to stop it.
