In a city this size, a 15+/- MILLION dollar jump in what originally was a 16-million dollar mayor/manager building (can't call it a city hall because it has no city offices except for the two luminaries' staffs) is criminal, and I use the term carefully. 
The fees paid the architects are completely out of the norm. Why? The demolition costs almost trebled: why? The fees to draw up unapproved and insanely expensive additions are way out of line with typical fees. Why?
I doubt it's mere incompetence, though that is a possibility. 
What actions are necessary to trigger a state's attorney general inquiry? I think we've reached any reasonable threshold.
