THE MORNING OF the second day of the general strike in San Francisco --Tuesday, July 17 -- found National Guardsmen, armed with rifles and a machine gun, manning a barricade at Jackson and Drumm streets, targeting the traffic in the first block of Jackson Street at number 65 where the Marine Workers Industrial Union (MWIU) had its office. Word of possible trouble had barely reached the MWIU office when a gang of men crashed through the front door. Some wore police badges; some were in plain clothes. An eyewitness recognized one as "Captain Malloy," presumably the same man soon identified in newspaper reports as the police officer who led the "posse" in several of the daylong series of "Police raids on Radical Meeting places." The raiders smashed typewriters on the floor; demolished desks; grabbed piles of stationery, receipt books, or whatever objects lay within reach; and looted the seamen's baggage room. The Examiner said the posse captured an "arsenal" of razors, axes, knives, and clubs, along with piles of "inflammatory literature." At the point of guns, men who were threatened by blackjacks and cursed -- "you red son of bitches," "get the dirty bastards" -- were held in a back room until the patrol wagon arrived. Nearly a hundred, under National Guard guns, were loaded in the wagon and taken to Harbor police station.
