Washington, February 19 (RHC)-- A new report released in the United States shows that the number of school shootings in the U.S. continues to grow following a rampage at an elementary school in Newtown, Connecticut, in 2012, which left 26 children and staff members dead.

Since the tragic shooting at Sandy Hook Elementary School, 44 more shootings have occurred at U.S. primary, high schools and universities -- approximately one every 10 days -- killing 28 people, according to a report released on by Moms Demand Actions and Mayors Against Illegal Guns.

According to the report, 75 percent of the shooters brought guns to schools from home. These guns included semi-automatic handguns and shotguns that were not properly locked or stored at home. The report also showed that the majority of recent shooting incidents at U.S. schools were ignited by arguments which later escalated into gunfire with young people fighting especially when jealousy or alcohol use was involved.

Since the Sandy Hook shooting, the U.S. congress has passed no legislation which would prohibit or even reduce the use of guns. And yet, the National Rifle Association, the most powerful pro-gun lobby group in the United States, has petitioned the U.S. Supreme Court over a federal law that bans licensed gun dealers from selling guns to people younger than 21.
