Gun violence is one of the acutest social problems in the U.S. According to the latest data by Gun Violence Archive (GVA), an American nonprofit group with an accompanying website and social media delivery platforms, 72 mass shootings have taken place in the U.S. so far this year. Frequent shootings have seriously violated people's right to life, leaving an indelible stain on the country's human rights record. The U.S. is the country with the most civilian-held firearms. In 2017, about 393.3 million guns were privately owned in the U.S., which means 120.5 firearms for every 100 people. The country ranks first in the world in terms of both individual gun ownership and the number of guns per capita.
