John didn't head home after the rally, he followed the Klan back to their bar, and photographed that evening's cross (and swastika) burning. For more info, please read the description ("show more") on John's flickr album.
A disclaimer from John:
"This set of photographs is NOT an endorsement of the KKK, the National Socialist Movement or any other hate group. I do not agree with anything they say. These images are documents of what happened in Rome, GA and later in Temple, GA on Saturday, April 23, 2016. This is a photo essay describing the events of the day. I am a social documentary photographer and not a member of any of these groups."
