How is law used to manage conflict, protect individual rights, and serve the common good in american society?

in all honesty, it really hasn't. except that hitler killed himself.

in 1897, pershing became a tactical officer at west point, and that's where he was given the nickname "black jack." pershing's first name is "john," for which "jack" is a nickname, and he was a white man who commanded black troops. hence "black jack".
