When the protest in Haymarket Square ended, the police arrived to disperse the crowd. When the police passed a person who was never identified, he threw a bomb at them. The police and possibly some members of the crowd opened fire and there was chaos. Seven policemen and at least one civilian died as a result of the violence that day, and an unknown number of others were injured. As a result of this incident, employers became suspicious of the unions and associated it with violence. The general public shared the same opinion.
