What works

摘要

THE young people who will march to protest against gun killings in Washington, DC and other cities on March 24th would appear to be wasting their time. Since December 2012, when Adam Lanza murdered 20 children and six staff at Sandy Hook Elementary School, America has experienced some 240 shootings that injured or killed people on school or college campuses. From 2012 to 2016 fully 108,100 people used guns to take their own lives and 63,600 were shot dead by others. Yet the House of Representatives has not voted on a single measure to prevent gun violence, let alone passed a law. In some states the law has loosened. Students at public colleges in Texas can now carry concealed handguns.
