...despite the DINOs who currently run the city.
On May 3, 1886, violence erupted at the McCormick Reaper Works during an assembly of strikers. That evening a small group of anarchists met to plan a rally the next day in response to the McCormick incident.
The rally began about 8:30 p.m. May 4 at the Haymarket, a site on Randolph between Halsted and Des Plaines Street, but due to low attendance it was moved a half block away to Des Plaines Street north of Randolph Street. After 10 p.m., as the rally drew to a close, 176 policemen led by Inspector John Bonfield moved in demanding immediate dispersal of the remaining 200 workers. Suddenly a bomb exploded. In the chaos that followed shots were fired by police and perhaps by workers. One police officer was killed by the bomb, six officers died later and sixty others were injured. No official count was made of civilian deaths or injuries probably because friends and/or relatives carried them off immediately. Medical evidence later showed that most of the injuries suffered by the police were caused by their own bullets.
All well known anarchists and socialists were rounded up and arrested in the days following the riot. Thirty one of them were named in criminal indictments and eight held for trial.
Although the bomb thrower has never been identified the eight indicted men were convicted by a court which held that the "inflammatory speeches and publications" of these eight incited the actions of the mob. The Illinois and U.S. Supreme Courts upheld the verdict.
