Thanks to the Dean of Cincinnati from the Cincinnati Beacon for the heads up on Facebook on this, the original wording coming from the Examiner, though I can’t find other sources to confirm. On June 30, 1979:
A group of 40 people in Cincinnati Ohio who had reserved a city park pool for a gay pride party were outnumbered and attacked by local residents who threw rocks and bottles at them. Police arrived, watched for a while and then drove away. One man had to be rescued by a television news crew. Police refused to return, even after several calls reporting a riot.
I have a feeling at least one of my readers will be able to confirm this, or know someone who can confirm this so we can get an interview and learn more about the incident???
