Since wearing face masks became mandatory in some states, several clashes between security guards trying to enforce rules and customers stuck to their opinions have been reported.
On July 5, a California security guard has fatally opened fire at a customer who refused to wear a mask and insisted to enter a market. Umeir Corniche Hawkins had multiple times fought 50-year-old Jerry Lewis and asked him to leave, but the stubborn customer returned again and again.
Hawkins has been charged with murder and possession of a handgun in connection with the fatal encounter while his wife, Sabrina Carter, was hit by one count of possession of a handgun. Both of them pleaded not guilty to the allegations.
