Is the account of the haymarket riot biased towards the workers or the anarchists?

On May 4, 1886, a labor protest rally near Chicago’s Haymarket Square turned into a riot after someone threw a bomb at police. At least eight people died as a result of the violence that day. Despite a lack of evidence against them, eight radical labor activists were convicted in connection with the bombing. The Haymarket Riot was viewed a setback for the organized labor movement in America, which was fighting for such rights as the eight-hour workday. At the same time, the men convicted in connection with the riot were viewed by many in the labor movement as martyrs.
