The search warrant was for the girl, the man, and any and all documents pertaining to the marriage and child. The judge also allowed CPS workers to go into the compound to talk to the occupants. CPS workers do not need a judge to do this - they need a citizen complaint, which they had already. The judge arranged LE protection and coordination.
When a complaint comes in to CPS that they deem a child is in imminent danger, they must make contact with that child to determine what is going on. They HAD to go into the compound to contact her. At the same time, they have leeway to talk to her family and friends to see how she is, how she has been treated, etc. Same as in any other child abuse investigation. As they begin their investigation "something" happened that led them to believe that none of the children were safe at the compound, and the judge said for all of them to be removed in order for the interviews to be continued away from the compound. Again - nothing any different from any other child abuse case.
So now, we have LE looking for the evidence cited in the search warrant, and it can't be found. Leaders refuse to allow them access to the temple. LE brings in equipment, including medical, in case something drastic happens, and heavy equipment to break down the doors of the temple if necessary. Again, nothing "illegal" - they have a legal search warrant for the entire compound, including the temple, and are now being refused entry. Same thing would happen if parishioners of my Methodist Church refused LE access to it and they had a search warrant. Especially if the rest of the scenario was the same.
I don't see this as any different than any other crime scene. It is what it is. A possible (probable), crime scene. It just happens to be at a large religious site. A crime perpetrated on "religious" property is still a crime. And the investigatiion into that crime is going to happen the same way any other crime is investigated.
They can't hide behind their religion. Nor could I, nor could you, nor anyone else here.
