Honestly, I don't think you have a clue how this process works.
First, private security guards can carry guns legally but Disney does not permit their own security guards to carry guns onto their property, which is the company's right. To be clear, there are a few exceptions but WDW prohibits cast members from bringing guns in their private vehicles to work, let alone clocking in with them. What you have are OCSO deputies who are working overtime,
getting paid by OCSO. Disney, in turn, pays OCSO for these deputies' time. Thus, the officers are not on Disney's payroll. If they were, it would open up the can of worms I described earlier, where Disney security personnel are acting as a law enforcement agency. Thus, Reedy Creek is increasing the budget to OCSO, so that they may have more of a staffing presence on property. Please see the original article which led to this thread:

I don't know where you are getting YOUR facts but OCSO has been the long-time law enforcement agency supporting Reedy Creek and there have been deputies on hand at each park backstage since at least the 90s. Can't tell you how many times during my many years working there I had to work with the deputies to deal with a law enforcement issue as it related to park guests. The issue with the chase was that, prior to 1994, Disney did not use OCSO for nearly anything, nor did they permit them (or FHP) on property for traffic services, etc. After this incident, they massively cut back on what Disney security was and was not allowed to do, also massively altering their appearance (giving them the "ice cream salesmen" costumes you see today, changing the light bars, etc).[/
