David Becker tells the tale of terror during the Las Vegas mass shooting at a country music festival – The Washington Post

“After capturing photographs of the final act of the Route 91 Harvest country music festival, I headed back to the media tent to start filing my photographs.  After about 5 to 10 minutes I heard very loud popping sounds and I went outside to see what was happening and a security guy said it was just firecrackers, so I went back to work. The second time I heard the popping sounds, somebody said to me, “It was just speakers or sound equipment,” and again, I went back into the media tent. Then the noises went again, and that was when the crowd started to flee.
