Is this American society capable of reasoned decision making?

We have been catapulted out of the realm of the reasonable and into very sick civic space where many believe that guns should be available to all who have not been proven to be mentally incapable of using a gun in a reasonable manner. Anyone who believes this to be sane policy should be on the list of those who need to be examined before being allowed to possess a deadly weapon. Those who are mentally ill often are not certified as such and they do not tell those who serve them that they are mentally ill, particularly when attempting to purchasing items that should not be in the hands of those who are not rational in their thinking and actions. Our society shows serious signs of suffering from collective mental debility each time one of these frequent events occurs and nothing is done to prevent them happening into the future. We have a long way to go to get close to sane.
