Juanita Young, whose son was killed by New York City cops, is one of the organizers of a Free Mothers Day event at Hostos College, in The Bronx, this Saturday. “You’ve got people’s sons who’ve been murdered through gun violence; you’ve got young men locked up for these police raids,” said Young, whose group is called The Motherhood. “What is going on, that the system feels that our loved ones’ lives have no value?”
