That period of time led to significant changes in institutional injustice.    While 'the law' can help change behaviors, it is not the perfect way to change the values of any one individual.   Too many people supported 'the law' while not always building relationships..  Paying tax's or donating money took the place of riding a bus next to a black man.   It beat doing nothing at all, but only moral arrogance would say it solved all problems.

Still the nation is better place for those souls who were motivated by compassion.    Some of the institutions came with serious faults and negetive outcomes, such as the destruction of families that has substituted a father with the hand of goverment, in poor famlies of all colors.    Good intentions with negetive results.    

A positive for PE Trump, he has forced both friends and foes to re-examine old habits and failed conventions.
