At UNC Charlotte in North Carolina on Tuesday, April 30, a 22-year-old man allegedly shot six people in his anthropology class with a handgun, wounding four and killing two. Three days earlier, on the last day of Passover, in Poway, California, a 19-year-old man walked into a synagogue with what police described as an “AR-type assault weapon” and now stands accused of killing a 60-year-old woman and injuring another congregant, the rabbi, and an 8-year-old girl.
