What noose am I tightening? Baby sitter has concerns. Someone calls gov't. Gov't contact Dad who refuses them entry. Tells them that kid has quack diagnosis. Gov't knows that quack diagnosis leads to quack treatments. Dad hides kids from gov't. What do you expect them to do?
We expect them to use juries or fair investigations of all sides.
Give me a grand jury and I indict you 3/4 of public schools and Family court workers on charges of cover up, perjuries, obstructions of justice, child endangerment and abuse... PERIOD.
