1700s The earliest known United States shooting to happen on school property was the Pontiac's Rebellion school massacre on July 26, 1764, where four Lenape American Indian entered the schoolhouse near present-day Greencastle, Pennsylvania, shot and killed schoolmaster Enoch Brown, and killed nine or ten children (reports vary).
That is such a lie.
The first entry on that list is an attack by indigenous peoples. The rest are basically all what we could consider a school shooting.
