Considering that it has been passed into law that Corporations are people, Then Said "people" should be held accountable for Crimes committed As any other person would be. Since In this case a "corporation" is now a collective "person," much as a human is a collection of millions of individual lives called cells, Said Members of a corporation (cells) should all be incarcerated and/or punished, exactly as all cells of a human being are.
If a human beings liver cells are not exempt from being locked away for assault committed by the hand cells, then a board of directors should not be exempt for crimes committed by their collective person either.
