May 4, the awful Haymarket Square Bombing in Chicago
A frame-up ensued and all the men targeted by the police were found guilty: August Spies, Albert Parsons, Adolph Fisher, Louis Lingg and George Engel were given the death penalty; Oscar Neebe, Samuel Fielden and Michael Schwab were sentenced to life imprisonment. On November 10, 1887, Lingg committed suicide by exploding a dynamite cap in his mouth. The following day, Parsons, Spies, Fisher and Engel were executed.
In 1889, a 9-foot tall bronze statue of a Chicago policeman was erected near the site of the riot, becoming a subject of debate and derision. After being moved from its original location, it was blown up at least twice by the Weather Underground before being moved to the lobby of police headquarters.
