Major plot hole
A basic idea that drives the plot in this movie--that an agreement with contractors will automatically pave the way for the destruction of public housing and the construction of high rises in NYC (or anywhere else in America for that matter)--is utterly ridiculous. A private contract like that creates no public agency approvals for a project. These days even far, far more modest projects go though literally years of studies, public hearings and pile after pile of revised drawings and plans--all mandated by myriad local, state and federal agencies. (It is BTW an extremely time consuming, risky, costly process, which all of us pay for when we buy and rent our homes or procure goods and services.)
In this movie Mayor Hostetler committed a number terrible crimes, but the result of his being an officer of a corporation that signed a contract for a project is simply that he had a conflict of interest. Moreover, having a conflict of interest is not by itself a crime so long as the public official recuses him or herself from taking any official action concerning a proposed project.
Apparently, the writers, producers and director of this movie have never tried to shepherd a proposed project through today's labyrinth of procedures mandated by public agencies.
