I don't know skr.
I have seen/read far too many horror tales about CPS to trust their judgment. There must be a happy medium, but I don't know what it is. I suppose the real problem is a combination of the failure of common sense, and the corruption of power. Some of these people get far too enthusiastic in their enforcement of these laws.
That's why I said the investigation phase should've been limited to priors and the context of the other photos from that film. The family didn't even have to know, if the police had just done that logical bit of investigation. As it is, the police certainly did go too far.
