When two loud bangs rang out on the streets of Lafayette, Louisiana, no one knew where the gunshots came from as protesters gathered to demand justice for another Black man killed by police.

Among the crowd was a group of armed Black men and women who call themselves the “Not F**king Around Coalition” or NFAC. The group did not run toward the gunshots or break formation. Instead, they kneeled on the ground amid the confusion, and then walked away after their leader shouted, “fall back! fall back!”

The all-Black, Atlanta-based group has grown in size out of frustration during a summer of protests against questionable policing and the deaths of countless Black people at the hands of police, said their founder John Fitzgerald Johnson…

“We’re not ‘effing’ around anymore with the continued abuses within our community and the lack of respect for our men, women and children,” Johnson told CNN.
