When firetrucks blew through the small town of West, Texas, on the evening of April 17, 2013, sirens screaming, naturally everybody was curious. People got in their cars and went to see the fire at the West fertilizer plant. For 10 minutes, they watched from cars and backyards as the fire grew ever bigger. A few moved as close as they could because they were filming on their smartphones. At no time did it occur to anybody that they might be in danger.
