Saturday marks one year since the massacre at Sandy Hook Elementary School that killed six educators and 20 first-graders. On Thursday, relatives of gun violence victims from around the country gathered for a vigil at the National Cathedral in Washington, D.C. Gilles Rousseau, father of slain Sandy Hook teacher Lauren Rousseau, addressed the gathering.

Gilles Rousseau: “We are here today with the common goal of remembering our loved ones and seeking to make our world a safer place. Acts of kindness and efforts to promote just cause are the best way to keep the memory of the victim of gun violence alive. I will remember.”

Crowd: “We will remember.”

Since Newtown, Congress has not passed any legislation on gun control, apart from the extension of a decades-long ban on plastic guns. A recent New York Times analysis found nearly two-thirds of gun laws passed by states since Newtown have loosened gun restrictions.
