If state inspectors who regulate Florida's amusement park and carnival rides want to explore why a 4-year-old boy died earlier this week after going on "Mission: Space" at Walt Disney World, they'll need permission from the theme-park resort.

That is because Disney World, and the state's other large theme-park complexes, Universal Orlando, Sea World and Busch Gardens Tampa, are exempted from most requirements of Florida's laws regulating carnival and smaller amusement-park rides.

"Our authority is limited by the statute," said Rob Jacobs, chief of the Bureau of Fair Rides Inspection. "We don't have the authority to close the park down or close the ride down."
