You raise a very good point. Many have blamed the availability of guns for these mass shootings.Guns have been a part of American culture forever, yet these rampages were almost nonexistent in the days when guns were everywhere and there were no gun laws. Poverty has been blamed as well, yet there were not mass shootings during the Great Depression. There have always been mentally ill people as well. The differences I see between now and then are the rejection of biblical values, moral decay, the breakdown of the family, failure to discipline children, and a devaluation of human life.
