Yet another mass shooting in the US forces us to ask the question: is this a growing problem? This graphic below depicts a snapshot of mass shootings in the United States since 1991. Friday’s Aurora, Colorado shooting at a movie theatre claimed the lives of 12 people and injured 59.
These 16, apparently random, acts of violence that have taken place in the last 21 years have increased in amount. From 1991 to 2001 there were 4 shootings, while in the last decade there have been 14 shootings, totaling 135 victims.
The shooters, all male, varied in age ranging from 11-year-old Andrew Golden who shot four girls and a teacher with Mitchell Johnson (13-years-old) in 1998 to Terry Ratzman and Mark Barton, both 44. Ratzman was responsible for gunning down members of his congregation in Wisconsin in 2005 while the Barton killed nine people in Georgia in 1999.
Out of the 18 shooters, 12 committed suicide directly after the attack while one, 18-year-old Sulejman Talovic, was gunned down by police at the Trolley Square mall in Salt Lake City, Utah. Alleged Aurora, Colorado shooter James Holmes is currently in police custody.
No over arching trend can be defined to explain why the shooters committed these acts.
