Beet,
You are splitting hairs about the private property.
In most states in the U.S. private property is constantly being argued in these terms due to police stops and searches of vehicals. The court in Oklahoma will have to decide the issue of a car as private property vs. a company demanding the greater right to dictate to it's employees what they can or cannot store in thier private property.
In Oklahoma firearms are legal tools. The interior of the employees cars are thier private property. It may even be private at the level of the castel doctrine. In the end, the private company may have to stop providing parking on their property for everyone. After all there becomes an opening for a class action suit of discrimination if they say car owners who store one class of legal tool in their car, cannot park on company property. But all other citizens can.
After all, in the U.S., because of our legal system, to discriminate against a group of law abiding citizens by a specific item or charateristic that is constiutionaly protected, can be argued legaly as discrimination against a civil right.
The ability to protect ones life is the most fundimental of all civil rights. Remember, a corporation is not a citizen with civil rights. One thing american corporations really don't like getting into court over is civil rights. When they loose, all american corporations loose with them. Class action suits sprout out of the walls.......................
This will drag on, especially since Oklahoma is a state that strongly beleives in the 2nd amendment and the fundimental right of protecting ones life and property.
