A grocery store customer, enraged that he was asked to wear a mask, allegedly shot and killed a cashier and injured two other people in a supermarket near Atlanta, according to multiple reports. Eyewitnesses told Atlanta news station WSB-TV Tucker had refused to put on his mask. The owner of the store told WSB-TV the deputy had been hired to help enforce mask policies. Last May, a security guard at a Dollar Tree discount store in Detroit was shot and killed after refusing entry to a woman who would not wear a mask. Grocery store and other essential workers have also been some of the most at-risk and vulnerable people during the pandemic.
