Its my choice. I can choose weather to respect a policy or not. In most instances I choose not to because it reduces my ability to defend myself and my loved ones. Being on crutches has greatly diminished my ability to defend myself or loved ones without a weapon. There are plenty of armed people that I trust at my fathers office there are not in walmart. That's the difference. I respect their ability to provide a safe environment not the no weapon policy.
The law has given me the freedom to make that choice. If they make it illegal for me to carry in places that have no weapon policies then I will no longer go there. As long as I have that freedom I will exercise it and I will encourage others to do the same. I would not encourage others to break the law regardless of my feelings of said law.
