Following the violent protests that killed three people and injured scores in Charlottesville, Virginia, users on various social media channels are trying to identify people who allegedly participated in the white nationalist rally. Peter Cvjetanovic, a 20-year-old student attending the University of Nevada, Reno, also had his image and identity spread across the Internet, to which he said he understood that the photo had a "very negative connotation." [...] not all photographed individuals appear to have been correctly identified, and some now-deleted tweets may have contained "potential private info," raising ethical questions for the campaign.
