Mass shootings in public have increased at an alarming rate over the past three decades and have become a growing concern for the people of the United States. It seems like every few months or so the media reports incidents of tragedies involving a single gunman targeting groups of people with the intent to harm or extinguish life for various reasons. Recent research data has indicated that since 1983, over 80 public mass shootings have occurred in the United States. Some of the most recent shootings to date are: Marysville-Pilchick High in October 2014; Santa Barbara, California, May 2014; Fort Hood, US Army base in Texas in April 2014; Washington Navy Yard in September 2013; Sandy Hook Elementary, Connecticut in December 2012; In 2013, research conducted by the Congressional Research Service (CRS) defined public mass shootings as events that occurred in a public place in which four or more people were injured or died from gunfire. The CRS also argued that the gunman typically selected victims randomly. J. Harris and R. Harris (2012) defined public mass shootings as savage violence. Ironically, following each tragic public shooting identified above, there have been heated debates about gun control among political pundits, government officials, and the American people, deliberations about the influence of media and entertainment that glorify violence, gaps in mental health services and a commitment to addressing the problem but to no avail. Because no progress was made in addressing public mass shootings, it was concluded that current research on mass violence was ineffective and required some modification (J. Harris & R. The answer to survey questions will be given through an extensive literature review and analysis. It is hypothesized that looser gun laws will predict a higher rate of mass shootings in public involving adult males aged 18 to 35 with untreated mental illnesses Meanwhile, untreated mental illness of males aged 18 to 35 predicts a higher rate of mass public shootings than those of other adult males who do not suffer from mental disorders
