LV警察最新报道，枪手在酒店内对保安连续开枪6分钟后才对音乐会群众开枪。在这6分钟时间内，为啥广场无人逃跑？

As questions spiral about a significant shift in the timeline of the Las Vegas shooting, a security guard stands in the middle of the controversy: Jose Campos. 

At first, Campos, a guard at the Mandalay Bay Resort and Casino, was hailed a hero for helping guide police to gunman Stephen Paddock's room on the 32nd floor. Police said Campos was shot in the leg at the end of Paddock's assault on concertgoers—potentially distracting the gunman and causing him to panic and kill himself. 

But now, questions have been raised after Clark County Sheriff Joe Lombardo revised the timeline and said Campos had actually been shot about 9:59 p.m.—a full six minutes before the mass shooting began at 10:05 p.m.—which means the guard could have instead led Paddock to start opening fire on the crowd for fear of being caught.
