The District does not have a police force, instead allowing Orange County and Osceola County to respond to incidents. The approximately 800 security staff are instead considered employees of the Walt Disney Company. Arrests and citations are issued by the Florida Highway Patrol along with the Orange County and Osceola County sheriffs deputies who patrol the roads. (Which they seem to do quite frequently, and with a fair number of traffic stops.) Disney security does maintain a fleet of security vans equipped with flares, traffic cones. These security personnel are charged with traffic control by the RCID and may only issue personnel violation notices to Disney and RCID employees, not the general public.
No, private companies should not be allowed to create their own jurisdictions. Without accountability, private companies are able to break land use laws without repercussions. No person nor company should be exempt from state laws created for regulation. How can one determine if violations are being committed if private companies are exempt from land use laws?
With the exception of Disney, companies should not be allowed to create their own jurisdictions. In Disney's case, they are also acting as a wildlife refuge which makes it acceptable in their case. For all other for-profit companies, creating their own jurisdictions could lead to corrupt and illegal policies that would only benefit them.
Except in certain cases, private companies should still be made to obey the land laws of their region. This can help to prevent unfair practices or advantages which private companies might be able to gain over their competition in the region. Preventing them from creating their own jurisdictions could be very useful.
