After a deadly shooting at a church in South Carolina last week, U.S. politicians are again debating how to deal with gun laws and gun violence.The Centers for Disease Control and Prevention reported that more than 11,000 people died and 84,000 people suffered injuries from gun violence in 2013.The CDC also reported that another 21,000 people committed suicide with guns. Currently most adults in the U.S. can legally buy guns.The Swiss group, Small Arms Survey, said in a 2007 report that more civilians in the U.S. own guns than civilians in any other country.President Barack Obama commented last week on how easily Americans can buy and keep guns.He was speaking about the man who is charged with shooting and killing nine people at a South Carolina church last week.The suspected shooter, Dylann Roof, appears in photographs that include white supremacy symbols.White supremacy is a belief that the white race is better than all other races and should have control of all other races.
