Without seeing the actual statute, I wouldn’t think that the right to make a citizens arrest would eliminate the citizens responsibility for their actions during the “citizens arrest”. Now I don’t think the statute is in question at this point, I think it has been established that these guys were not actually even in compliance with that particular statute, so it should be a moot point anyway, but even if they had seen the gentleman actually commit a crime, I don’t think looking at the video and from the story as it has been presented so far that even IF they were in compliance with Georgia’s “citizen arrest” law that this homicide would be considered justified.
