Police raids were made on some of the "Black Belt" clubs on August 23. At the Ranier Club, 3010 South State Street, two revolvers, one razor, one "black-jack," seven cartridges, one cattle knife, and one ordinary knife were found. At the Pioneer Club, 3512 South State Street, eight guns, four packages of cartridges and twenty-four knives were taken. A raid at 2700 South State Street netted four guns, one hunting-knife, and fifty-eight cartridges and bullets.
The foreman of the grand jury which investigated the riots discussing the "athletic" and "social" clubs before the Commission, said:
Most of them were closed immediately after the riots. There were "Ragen's Colts," as they were known, concerning whom the grand jury were particularly anxious to get something concrete, although no evidence was presented that convicted any of the members of that club. There were the Hamburgers, another athletic club, the Lotus Club, the Mayflower, and various clubs. These were white clubs.
Asked if they really were athletic clubs, he replied:
I think they are athletic only with their fists and brass knuckles and guns. We had Mr. Ragen before the grand jury, and he told us of the noble work that they were doing in the district, that Father Brian, who had charge of these boys, taught them to box and how to build themselves up physically, and they were doing a most noble work, and you would think that Ragen was a public benefactor. During the deliberations of this grand jury a number of anonymous letters were written with reference to "Ragen's Colts," and most of the explanations of the fact that they failed to put their names on these letters were that they were afraid they would lose their lives.
The grand jury included in its report this reference to the gang and club phase of the riot:
The authorities employed to enforce the law should thoroughly investigate clubs and other organizations posing as athletic and social clubs which really are organizations of hoodlums and criminals formed for the purpose of furthering the interest of local politics. In the opinion of this jury many of the crimes committed in the "Black Belt" by whites and the fires that were started back of the Yards, which, however, were credited to the Negroes, were more than likely the work of the gangs operating on the Southwest Side under the guise of these clubs, and the jury believes that these fires were started for the purpose of inciting race feeling by blaming same on the blacks. These gangs have apparently taken an active part in the race riots, and no arrests of their members have been made as far as this jury is aware.
