We chat with Chicago freelancer Ting Shen about his quest for the perfect camera strap, shooting NBA basketball and his experience covering the Dallas police shootings. On July 7, 2016 four Dallas police officers and one DART officer were gunned down on the streets of Dallas, Texas. Ting, who was working as the photo intern for the Dallas Morning News, was sent to Baylor University Hospital. He recounts the events which led up to making the unforgettable image of a DART police officer comforting a colleague in the emergency room entrance. He also discusses the lessons learned in the wake of the tragic event. http://interactives.dallasnews.com/2016/rally-shooting/
