The media often treat events as if they are new — something unprecedented. A good example is the issue of mass shootings. Each time one hits the news, it is treated as something that, if not new, is a recent development.
However, one doesn’t have to look very hard to find many historical examples. It took only about a half hour to find the following. And, to keep things on a relative apples-to-apples basis, this shows civilian on civilian cases only. It excludes examples perpetrated by soldiers, police or other government authorized actions or civil wars. Only events prior to 1970 are listed; many more examples could be added to the list.
