So just exactly what does that statement mean? "Follow State Law" doesn't really mean anything as there is no State Law requiring them to allow firearm carriers on their property.
State Law does, however, give them the right to ask one to leave and if that person refuses then file a trespass complaint against them.
This "follows State Law" discussion has been chewed more than a street hooker's bubblegum.
Are you being intentionally obtuse? I have to think that if you are familiar with the discussion of these policies here then you still don't have a clue what they are about.
All this means is that the company has a policy of allowing firearms on their property as long as the firearms are carried in a manner compliant with state law.... In other words, so long as the carrier "Follows State Law".
That being said, what this mean in real life when you walk into a given store of a company that has this kind of policy is NOTHING. If you walk in the store OC and the first employee to see you asks you to leave you have to leave. Get their name and call the store management and get it straightened out. After you have the store management straightened out walk into the store again, and if that same or another employee asks you to leave then you have to leave. If you get it finally straightened out for real, and you go to the store every day for 5 years straight without incident, and then one day an employee asks you to leave... you have to leave. The existence of this kind of policy, and your knowledge of its existence, will never be a defense against a trespassing charge.
Also, State law does not give shopkeepers any right to trespass someone. That is a natural right of the shopkeeper, as natural as the right to keep and bear arms, or trespass someone from your home. The only thing that we the people (the first branch of the government) allow the State to do is limit this right in necessary ways for the betterment of society, such as not letting you trespass someone from your business based on their race, gender, religion, etc.
