The resilience of these women, men and children in fighting to protect their human rights must not go unnoticed. We must continue to challenge the existence of these centers and force the President to acknowledge that detention worsens the trauma migrants have to live with and to recognize that detention is far from a humane response.
Detention has been widely decried by human-rights advocates for its prison-like conditions and the too-frequent abuses that are visited upon the detained. But the truly horrifying aspect of this system is how it's being used and expanded to detain the mothers and children who have sought asylum in the United States.
Children are by definition vulnerable. That's particularly true for girls and boys journeying alone, under unsafe circumstances, often fleeing violence. Mexico and the US have an obligation to apply the international principle of the "best interests of the child" as the gold standard for all dealings with underage migrants.
