In FBI murder data, mass killings often go missing
USA Today - 09/11/2014
When 26 teachers, students and administrators were shot to death at Sandy Hook Elementary School, it made national news for weeks. But there was one place 2012’s largest mass killing was never mentioned: the FBI database that tracks all U.S. homicides.
And that isn’t the only major case missing. The 12 people who were killed in an Aurora, Colo., movie watching the premier of a Batman movie aren’t listed either, raising questions about the accuracy and usefulness of the federal data.
