Barack Obama quotes
The arc of the moral universe may bend towards justice, but it doesn’t bend on its own. To secure the gains this country has made requires constant vigilance, not complacency. Whether it’s by challenging those who erect new barriers to the vote or ensuring that the scales of justice work equally for all in the criminal justice system and not simply a pipeline from underfunded schools to overcrowded jails — it requires vigilance.
