Complete speculation / MOO --
I've also been surprised by the concern for Lori's safety (kevlar? secret decoy vans? last-minute changes in travel plans?) Do they really expect anyone in the community -- which seems to be first and foremost concerned with finding the children -- to try to kill her without first finding out where Tylee & JJ are?
Or do LE/FBI know more about other groups involved that they're not saying? Early LDS temple oaths included vows (taken from Masonic rituals) not to reveal any of the sacred things that happened there, or else their "throats be cut from ear to ear and our tongues torn out by our roots." (
LINK) Although the mainstream LDS church has discontinued and disavowed these oaths, if these splinter groups believe that the mainstream LDS church is in apostasy, it wouldn't be too farfetched to think they might reinstate this type of secrecy vow.
Could LVD & CD be in danger from others in their splinter group who think they might reveal "secret/sacred" information in the court proceedings?
