Yes I have, but since your going to keep badgering me about it because your to lazy to look it up yourself, I'll spell it out to you.
How you carry doesn't matter. OC or CC your still carrying. Just because no one knows you have trespassed doesn't mean you haven't.
If you carry an unwanted item onto a property, business or personal, contractual or not, IS trespassing. I never said "immediate arrest", as the law states the person must be confronted first. Unless confronting the person presents a safety risk. But the right to arrest a trespasser is always there. Now, whether or not an officer will follow though is a differrent debate. But a property owner, business or otherwise, always retanes the right to have a have a trespasser arrested.
But lets say for a second that contractual interest does play a role. Now you have an obligation to follow the policies of the business to recieve their services. The policy is "No Firearms", but your carrying. Even if they don't notice, your still carrying thus still trespassing. Even if they don't ever catch on all thats happened is you have gotten away with trespassing.
Being confronted is there to resolve the matter at the lowest plossible level, not because you haven't done anything wrong.
Do you see my point yet?
I see your point. However, Indiana trespassing law makes it fairly clear that you have to be denied entry, or not leave when asked to. A sign that says "No Firearms" I don't believe constitutes denial of entry. The simple act of having to ask the person to leave a business before criminal charges are brought ought to be a no-brainer. Outside of that, the potential for abuse of the law would be just outrageous. For example, I post a sign that says "No t-shirts" outside my business. I don't enforce this because it's silly. A guy comes in with a t-shirt and pisses me off. He is now arrested and has a Class A misdemeanor on his record, even though he probably didn't notice the sign and was never asked to leave. If this is the sort of scenario that you think is perfectly right and acceptable...there's just no hope for you.
