The latest school violence in Virginia is sickening. The violence occurred in two different parts of campus at different time periods. Washington Post has a map of the shootings on the campus and Virginia Tech offers its own maps of campus (Hat tip: Map Room Blog).
The School Violence Resource Center has mapped out school shootings and stabbings from 1996 to 2006. The problem is clearly no longer centered in the Bible Belt but has spread out nationally. the only area free of incidents so far is the Northwest Interior ranging from the Dakotas to Idaho and adding in Utah and Nebraska.
