The following is also from the American Center for Law & Justice website. There is also a lot more information on this site -- too much to list here. I suggest everyone check it out for yourself at www.aclj.org
"In the Santa Fe case, a case involving prayer at football games that I argued a couple years ago, the Supreme Court did say that the school was too involved in the prayer activity, even in Justice Stevens' opinion. This is not overly helpful in any regard, except for one: the Supreme Court said that students have the right to pray before, during, and after the school day. And there's nothing in the Constitution, or the Supreme Court precedent, that denies that. So there are constitutional rights, even in the Santa Fe case, allowing students to pray collectively as a group. Students are allowed if they so choose-it's up to them."
