There are many ways to commit mass murder, with explosives, fires, chemical weapons, biological weapons, hijackings, trucks, knives, and so on. But far more dangerous than guns and other physical weapons are words, laws, and attitudes.
It has become clear that many if not most mass murderers have given advance notice of their evil intentions, either directly or indirectly, and the guns that have caused the mass shootings generally would never have been cocked and shot had people who had advance warnings not been afraid to notify authorities in advance of their suspicions. People are more afraid of being accused of profiling than they are of being responsible for shootings. People are more afraid of being wrong than of being shot. People are more afraid of hurting the feelings of others than of preventing mass murderers who deprive innocent people of their feelings on a more permanent basis – their lives – as well as the feelings of all who knew them and loved them for the rest of their lives.
