The worst school massacre in American history was committed at Bath, Mich., in 1927 and involved no firearms; a frustrated politician bombed the school.

The National Review reports on gun hysteria:

There is a national myth that this began with Columbine High School, but that simply is not the case. Nor is this an American phenomenon: In the past several decades there were 18 public mass shootings in the Philippines, 15 in Russia, ten in France, etc. There has been, by some estimates, an upturn in public mass shootings; at the same time, shooting deaths have declined by half in the past 20 years. This is a much safer country than it was in 1994.
