I believe it was reported that these two "camera watchers" are actually viewing all the security cameras in the courthouse. IIRC, someone mentioned that there were 30 or 40 cameras in the Fulton Co. Courthouse.
OK, if that's the case, I stand corrected.
A video camera, which is supposed to be monitored by two guards in a command post
I inferred there was only one ("A") camera from the first line of the story (should have known better not to take anything literally I read in the AJC...)
