On this date in 1919, eight bombs exploded in seven different US cities. The bombs, thought to have been the work of followers of Italian anarchist Luigi Galleani, were targeted at people perceived as outspoken critics of the anarchists. The targets, which included the home of Attorney General A. Mitchell Palmer (pictured above) were located in New York, Philadelphia, Washington DC, Cleveland, Pittsburgh, Boston, and Patterson, NJ. None of the intended targets was killed, but two innocent people died in the explosions.
The June 2nd attacks were part of a campaign of violence that began two months earlier. The Bureau of Investigation (precursor to the FBI) conducted an exhaustive investigation, but were unable to solve the crimes. Later that year, the Justice Department conducted a series of raids and deportations of immigrants believed to be a threat to national security.
