People raise white handkerchiefs, the signature symbol of the Mothers of Plaza de Mayo human rights group, during a protest against a Supreme Court ruling that benefited a man serving time for crimes against humanity in Buenos Aires, Argentina, Wednesday, May 10, 2017.

In response to the popular outcry, earlier in the day Wednesday, Argentina’s Congress approved a bill banning the reduction of jail sentences for people serving time for crimes against humanity.
