I've seen that too, Chris
My favorite was an independant therapist, who went into a home check with a case worker and a video camera. He would focus in on any "issue" the case worker pointed out: quite often, what the camera showed didn't match what the worker was describing
As they were leaving, he stopped the woman, and pointed out that everything she had accused the family of doing wrong, had been something that was present in HER household while she was growing up. ANd he had been her case worker at the time, so he would know...
