Disney
does not have armed security on property, nor do they have the ability to stop people on property in their vehicles. Anybody armed you see is either FHP, OCSO or Osceola County. While their agreement with the state does permit them to operate a police force, they have chosen not to do so, for a variety of reasons. Mainly, arresting people is not something Disney, as a brand, wants to be in. Secondly, the amount of legal liability is insane and the press that would result if a Disney security officer fired a weapon into a theme park would be a gigantic mess, particularly if it turned out, as many police shootings do, that there was no cause for the weapon to be discharged.
There's more of a backstory here than many might think. Previously to 1994, Disney security operated as more of a "private police force," conducting investigations, stopping cars, etc. Then an incident happened in 1994 where Disney security chased a guy whose car then ran off the road. The issue was problematic from a legal liability standpoint. However, it opened a much bigger can of worms in that Disney claimed their guards were essentially "night watchmen," and the court ruled as such. However, it was clear they were straddling a very fine line and it was possible that any further issues would force Disney security to be classified as a police force, thus subjecting them to public records laws. Opting to avoid this mess, they completely retooled the security department, where there they took on the mantra of "observe and report." It was also during this time that the security vehicles got orange "security"-type lights, as opposed to the more traditional police red, while the costumes got retooled to be more Disney-esque. From there, they increased their deal with OCSO to have more of an on-property presence.
