Although he had two bulletproof vests and two revolvers, the Rev. Martin Green, colored, pastor of a church at 4421 South State street, went to the offices of the Detective magazine yesterday and tried to purchase a Thompson machine gun [sic]. The police were notified and he was arrested. His only explanation was that he wanted to be sure he was able to protect himself and his congregation. Dr. William Hickson of the psychopathic laboratory is to examine the minister.

The 36-year-old reverend had come to the right place – “Al” Dunlap, editor of the magazine The Detective at 1029 South Wabash Avenue in Chicago, Illinois, had a thriving side business selling steel-lined Dunrite “bullet-proof” vests (GURPS High-Tech, p. 66; Investigator Weapons 1: The 1920s and 1930s, p. 49) of his own design and make, and Thompson submachine guns in .45 ACP (GURPS High-Tech: Pulp Guns 1, pp. 28-30; Investigator Weapons 1, pp. 87-89). Dunlap distributed no less than 65 of the submachine guns during the 1920s, at least three of which ended up in the hands of gangsters like “Fred Burke” or the Touhy Gang ‒ he was not always as circumspect about his customers as in this instance. John Dillinger’s favourite Model 1921AC submachine gun had originally been supplied by Dunlap to a sheriff’s office before it was stolen by Dillinger.
