Biography
David Rosen was one of nine Newark workers indicted under New Jersey's 1918 sedition law following police raids on unemployed-workers meetings on February 4 and 11, 1930. The Labor Defender of July 1930, page 139, names him and identifies him in a group photograph of the defendants. Three others had been sentenced; Rosen was among the six whose trial was announced for June 23. The International Labor Defense organized the defense. The source does not assign Rosen an individual arrest day or establish his eventual disposition, release date or time in custody.
The February 11 Newark dispatch identifies these workers among nine arrested at the unemployed meeting, 93 Mercer Street. Rosen had previously been out on bail after an earlier leaflet arrest, so earlier and current detention are not treated as one uninterrupted period. No exact discharge or completed total is supplied.
