"If a business owner wants to prevent guns on his property, he is entitled to
do so. The government has no business either helping or hindering him to do so."
Given the above, how do you propose the business owner do so?
If a property owner asks someone to leave and they refuse, I believe that is trespassing and the police are within their bounds to intervene.
Consider two scenarios:
1. You enter a restaurant with your dog. A sign says "No dogs allowed." The manager asks you to leave but you refuse to do so.
2. You enter a restaurant with your holstered gun in plain view. The manager tells you guns are not allowed and asks you to leave. Without threatening or touching the gun, you refuse.
Which will get the bigger punishment?
