From what I remember was that the kid was praying at lunch.Majin Tenshi said:Note: Stuff doesn't allways happen the way its supposed to.
Officialy lead prayer in schools = illegal
Private prayer = legal.
Some people over-react to Seperation to church and state, and think that a person must check their religion at the door when they enter a goverment affiliated building. Now, if he got up and tried to lead the class in prayer, thats a different story.
Edit: are you sure it's illegal or just not allowed? I don't think anyone is going to press charges on a kid for leading a prayer in his class, or want to put him in a jail cell with a kid that just killed his parents by setting the house on fire.
