I have to agree that I don't think guns belong on Disney property in the hands of Guests or CMs. If the OCSD has them on property, that's fine. But I see no reason to carry a gun with you in your car at all times.
Of course, in case you couldn't tell, I have never owned a firearm, and have never had a desire to. I have lived in some bad neighborhoods in New York, and currently live outside of Orlando, where the crime is pretty high, and my aluminium baseball bat will do nicely. If I need to defend myself, I will, but a gun would serve no purpose for me. If someone comes at me with a gun, they're either a) close enough that I can get them with that aforementioned bat, or b) far enough away that I can't hit them, in which case my only option would be to have a gun on me that I can aim and fire before they do, and the chances of that are not amazingly high.
Having a gun doesn't protect you from someone with a gun, IMHO. And I have to say that I'd rather Disney not allow CMs or Guests to bring guns on property at all. I feel safer without guns than with.
