My feeling that the TSA's motive is obvious has to do with the very
fact of their being a court case. To me this means that their general
motive has nothing to do with assisting the Tacoma Lodge "to become
better able to help and teach others". It is to rein them in from
their independence, as you mentioned, and bring them in-line with how
the TSA wants their Lodges to behave, regarding procedure. To me
there is nothing else to be seen regarding their motive, regardless
of how they put it.
And what behavior is it that the Tacoma Lodge is exhibiting that the
TSA does not wish them to exhibit?
