The 1927 bomber was a local guy who was ticked-off over his property taxes.
Unlike today in Florida, where the Parkland school building where the massacre occurred will be demolished, the school in the 1927 bombing was repaired, and the kids went back to classes there. The wimpification of America rolls on.
Even the news coverage of the 1927 bombing was truncated by Charles Lindbergh’s trans-Atlantic solo flight a few days later. Yes, there were news cycles before the internet.
