11 is a fairly odd point to pick a cut off. That article's referenced source (http://www.washingtonpost.com/wp-srv/special/nation/deadliest-us-shootings/ http://www.washingtonpost.com/wp-srv/special/nation/deadlies...) also has errors. It purports to list all 10 and above gun involved murder sprees, including cases back as far as 1949 (ignoring bombings, but whatever). It doesn't list Starkweather and Fugate's 10 person killing spree in 1957, or James Edward Pough's 1990 rampage in Jacksonville that killed 11 and injured 6, or Mark Barton's 1999 rampage that killed 12 and injured 13, or Leung Ying's 1928 California spree that killed 11 injured 4, or Nidal Hassan's 2009 Fort Hood spree killing 13, injuring 30, or Patrick Sherill's 1986 Oklahoma spree killing 14 injuring 6, or Ronald Simmons 1987 Arkansas rampage killing 16 injuring 4, or George Banks 1982 Pennsylvania killing of 13 injuring 1. Since the article leaves out so many well known cases it can not be considered reliable regarding its comprehensiveness. The other article which actually did complete counts of all known cases should be considered far more authoritative.
