Milwaukee Police Department bombing
The bombing remained the most fatal single event in national law enforcement history for over 80 years until the September 11 attacks.[2] A little over two months later, on November 24, 1917, a large black powder bomb wrapped as a package was discovered by Maude L. Richter, a social worker, next to Rev.[6] The police detective who faced the full brunt of the explosion was reported to have been found with his body mangled while one officer was killed while on the second floor.Those responsible were never apprehended, but days later the eleven alleged Italian anarchists previously arrested went to trial on charges stemming from the Bay View incident.At the time, the bombing was the most fatal single event in national law enforcement history, only surpassed later by the September 11 attacks.
