“Slacker Raids” Round Up Alleged Draft Evaders in WW I
“Slackers” was a label given to young men suspected of avoiding the draft in World War I. The “slacker raids” were a series of massive roundups of young men by government officials and private citizens based on nothing more than unverified suspicions, prejudices and stereotypes. In addition to the raids on this day, another set of massive raids occurred on September 14, 1917.
The private citizens were volunteers in the American Protective League (APL), a private organization of citizens who carried badges issued by the Justice Department but who had no legal authority to make arrests. Nevertheless, they detained and arrested people anyway. On the founding of the APL, see June 4, 1917.
