Not to mention, MOA doesn’t say in its sign WHAT law they claim they are using. That sign was written by an idiot liberal that doesn’t know the law. I suspect if a shooting happens there will be lawsuits based on that sign.
We had one of those types of signs at my office building. After the CT school shooting the manager of the building was asked if he was legally assuming responsibility for our safety in light of those signs. They came down the next day.
