United States is the only country in the world where civilian guns outnumber people, according to the Swiss base Small Arms Survey (SAS), and is also the country where at least one mass shooting takes place every year, as has tragically happened in Texas, where 19 school children and two teachers were killed by some mentally ill teenager.
Ten people were killed and 10 wounded in a shooting on Friday morning at a high school south of Houston, authorities said. The shooting at Santa Fe High School was the nation's deadliest such attack since the massacre in Florida that gave rise to a campaign by teens for gun control.
