Well, if you read the dissent, there are some facts that do not appear in the majority opinion. In essence, the coach at one point was acting inappropriately by saying prayers in pregame meetings with the students. However, he agreed to stop that. So now he just wants to pray at the 50 yard line. There is some dispute as whether he invites players or not.
And why does he want to pray there. It is because he wants the show. The coach and the District come to an agreement that he would be allowed to pray at the 50 yard line as long as students did not join him. Well, he then goes to the media and this thing now gets out of control. Here is part of the opinion:
"The District reiterated that “all District staff are free to engage in religious activity, including prayer, so long as it does not interfere with job responsibilities.” Id., at 45. To avoid endorsing student religious exercise, the District in- structed that such activity must be nondemonstrative or conducted separately from students, away from student ac- tivities. Ibid. The District expressed concern that Kennedy had continued his midfield prayer practice at two games af- ter the District’s athletic director and the varsity team’s head coach had instructed him to stop. Id., at 40–41.:
So the District allowed him to pray at the 50 as long as he didn't invite players and separately from the students. But then he goes to the media and blows this thing up.
The next game he prays at the 50 yard line and the students, parents politicians all go out to the 50 yard line with him. so it becomes a spectacle. I can see why the District was pissed off. These are bad facts that lead to bad law. This may have some serious consequences in the future. I am a little dismayed by the majority opinion leaving out pertinent facts of this case.
