Good question and interesting answers too.
I would add that initially and even before making Cry Macho, Clint wanted to make a legal drama anyway: I think of that Clarence Darrow project called Conviction, which did not come to fruition at this point. Juror #2, regarding the synopsis, seems old-fashioned, like many other Clint films. I think that it is a new occasion for Clint to explore and describe the American society through its legal system, its good sides and its dark sides: how does a man deal with the institutions of his country ? And also, how does he deal with his own consciousness ?
Juror #2 is promising and I am happy to see Clint making an other film.
