I think little Caylee, wherever she is, alive or not....(hoping and praying for alive of course), needs prayers.
I think everyone should be praying for her, whole churches praying for her, wherever she is, it will never hurt to gather and pray for her. If anyone in that area feels a need to pray for her with a group of people they would be better off planning it every week at a church near the Anthony's home, or at a mutual location.
I think the residents in their neighborhood are fed up with all of it, and until something is figured out with the protestors, there is no sense in adding fuel to the fire. The Anthony's could also pray with their church congregation on Sunday's when they attend, and that might help as far as them not feeling like they have to stop the group prayers all together.
Also I see no reason they couldn't hold it in their back yard. Have their bodyguard people out there, and if anyone comes on the property then call the deputies. Also if they don't invite the media back their then, I seriously doubt the media is going to just go break down their door or gate to get back their.
