"So many positive people helped me in my struggle," said Gwen Carr, the mother of Garner, who died on Staten Island after being put in a chokehold by police in 2014. "So I was able to get up and turn my mourning into a movement, to turn my sorrow into a strategy, my bitterness became my battle for justice. I stand here today and I'll tell you: It's not an easy thing. It's not easy at all."
