Is it true that their demonstration was 1,000 feet away from the funeral?
Yes, as a matter of fact, it is. That was in the trial court record and not disputed.
Which leads me to wonder what double standard Palin was referring to. Personally, I think prayer in school is fine, but to claim as she did that that denying prayer in schools somehow meant there was a "double standard" when viewed with this decision makes zero sense. The double standard would be not permitting prayer 1000 feet away from a church. Or school, I suppose.
