A coalition of left-wing activists soon moved into the woods after the decision was announced, according to the Atlanta Journal-Constitution, in a bid to prevent the construction.

Protests at "Cop City" hit a fever pitch back in January, when a state trooper shot and killed an environmental activist named Manuel Esteban Paez Teran, 26, who reportedly went by the name Tortuguita and identified as non-binary. Teran was shot after allegedly refusing demands from authorities and firing a gun at state troopers.
