A U.S. national flag flies at half-mast above the White House to mourn the victims of mass shootings in El Paso and Dayton, Washington D.C., the United States, on Aug. 4, 2019. The two mass shootings in the United States left 31 people dead and dozens injured. As the final days of the year approach, Americans are facing a grim milestone -- there have already been more mass shootings in 2019 than there are days in the entire year. As of Dec. 22, there have been 404 cases of mass shooting in the United States, according to the Gun Violence Archive (GVA). This is the highest number since the organization started collecting data in 2013. According to the GVA, 14,801 people were killed and 28,613 people injured by guns across the United States as of Dec. 22, excluding suicide. (Photo by Ting Shen/Xinhua)
