I think Jackie was the second shooter.

Can anyone recommend me any good books/articles about how wide streets/avenues were used to stop the public from rebelling? For instance in the french revolution there was a wide street constructed that went right through a rebellious neighborhood in order to break them up, and today Egypt is building a new administrative capital to insulate it from the growing population of poor and unhappy people in Cairo. Are there other instances in history like this you know of and any good books that might compare them? thanks
