For me its not just the policy but it is the Law. And its different when it is the law. I always try and obey the law as it is written not as one wishes to interpret it. And here, it simply is the Law that I cannot carry at work. All I can do is obey that and try and change the law. Some places of employment go beyond what is policy and have state laws (or federal laws) applied to them. If you worked in a Federal building you wouldn't chose to carry anyway. You would obey the law. Same thing with a State institution which had a clear State law prohibiting carry. Your only choice then is to get permission from the local authority or not carry, because it is the law. Much harder to do than just risk employment. Your risking a legal challenge too.
