The idea that Disney World has "hidden snipers" on the rooftops of Main Street or Cinderella Castle is one of the most persistent urban legends in the theme park world, but it is largely a misunderstanding of their security protocols. Disney does not have permanent, visible "snipers" stationed on roofs. However, they do have one of the most sophisticated and layered security operations in the world, which includes a heavy presence of undercover officers from the Orange County Sheriff's Office and Disney's own private security. While you won't see someone with a rifle overlooking the fireworks, Disney does employ "spotters" and uses thousands of high-definition cameras with facial recognition technology to monitor crowds. In the event of a high-profile visit from a world leader or a specific credible threat, the local police or Secret Service would indeed place tactical teams on rooftops, but this is not a "normal" day-to-day operation. Disney's goal is to maintain a "magical" atmosphere, so their most intense security measures are designed to be invisible to the average guest. They focus on prevention through metal detectors, canine units (bomb-sniffing dogs), and extensive perimeter monitoring rather than overt military-style displays.
