LIVINGSTON, N.J. (CBSNewYork) — A sizable crowd gathered at a synagogue in Livingston, New Jersey Sunday to hear three survivors of the Parkland, Florida school massacre speak. As WCBS 880’s Ethan Harp reported, Marjory Stoneman Douglas High School students David Hogg, Ryan Deitsch, and Matthew Deitsch all took part in a rally at Temple B’nai Abraham in support of what they call common sense gun legislation.
