Weekend of Shootings Leaves Trail of Death and Tragedy Across US

At least nine people were killed and dozens injured in a spate of mass shootings across the United States over the weekend, including a Pennsylvania state trooper. The shootings occurred in suburban Chicago, Washington state, central Pennsylvania, St. Louis, Southern California, and Baltimore. Researchers disagree over the cause of the increase in violence, with theories including the prevalence of guns in America and less aggressive police tactics. The shootings follow a surge in homicides and other violence over the past several years that experts say accelerated during the coronavirus pandemic.
