“Those sympathetic to the John Birch Society celebrated for a short period after the assassination. Then the upswing in public mourning made it unacceptable to celebrate in the wake of his death. In Biloxi, MS, for instance, the John Birch Society headquarters there had a local university student Thomas Hansen chew them out for their banners of celebration. They then shoved him through the front door glass and had him arrested for vandalism. Public shame had the charges dropped, and Mr. Hansen sported the scars from the glass door as a proud badge of honor.”
The author, Nathaniel Downes, says Hansen was his stepfather.
I would love to hear other accounts of Kennedy’s death being celebrated and any news coverage or commentary on the same.
