On August 5, 2012, a gunman entered a Sikh temple in Oak Creek, Wisconsin and opened fire. He killed six people and wounded four others. The shooting came just weeks after James Holmes killed 12 people inside a Century movie theater in Aurora, Colorado. These events would soon be followed by the tragedy at Sandy Hook Elementary School, where 20 children and six adults, were killed. "How can a human come in to a elementary school and have no empathy for six- and seven-year-olds?" said Amardeep Kaleka, whose father was killed in the Sikh temple shooting. "That is extremely disturbing on so many levels." This week, Amardeep and his brother Pardeep Kaleka, are in Punjab, India to lay their father's ashes in his ancestral homeland. They talk about the long journey that's taken them from Oak Creek to India and the stops they've made in between to advocate for stronger gun control laws in America.
