This'n'That; December Fifteenth #1; Prayers

Make Up Your Minds!!
    First we're told that it's unconsitutional to say the Lord's Prayer in public schools.... as well as the Pledge of Allegiance--but that's an another argument for another day!
    Then we're told that it's unconstitutional to say a prayer before sporting events at public facilities.
    Then we're told that it's unconstitutional to display religious messages in public buildings or on public grounds.
    Now, everybody'n'his brother; from the "Clown Prince" south, is telling us to pray for the survivors of the 'Sandy Hook Massacre.'
    Now, everybody'n'his brother; from the "Clown Prince" south, is telling us to pray for the souls of the victims of the 'Sandy Hook Massacre.'
Well, which is it?!?
Do we pray for the survivors as well as the victims?!?
Is it still unconstitutional to pray in public government buildings or on government grounds, but only unconstitutional in general terms?!?
Is it suddenly CONSTITUTIONAL when applied to a specific incident; a specific tragedy?!?
What's it gonna be?!?
Your comments?
