In the minutes that followed the first sounds of gunfire Sunday night at Bondi Beach in Sydney, the assault would end the lives of at least 15 people. Officials say that includes a 10-year-old girl, a Holocaust survivor and a beloved rabbi. It would also end a sense of security in a country that has largely been insulated from mass shootings because of strict gun laws. One mother attending a Hanukkah celebration recalls grabbing her son and hiding under a table. She watched as a man nearby was shot. He later died.
