Blondie, Rutherford's security force was described by journalists, too. The canes they carried were meant for crowd control. There was a cane incident at Madison Square, too, wasn't there?
From
the St Louis "Globe Democrat" 1941:
When he arrives at the Arena a double line of husky well-instructed men link arms to shield him. Efficient flying squads block any approach near him in the building, while at least two guard are on duty at each of four landings in the arena stairway leading to the fourth-floor administration offices.
The Judge takes the elevator. Others must walk, explaining their mission four times en route. Few survive the gauntlet. Rutherford said he tries to make himself available to any Witness, but his subordinates explain they are seeking to conserve his strength.
Before and after addresses from the speakers' platform, the guard is even tighter. He arrives only seconds before he begins to talk and is whisked to an automobile before the concluding applause dies out. The audience is cautioned not to whisper. Ushers have turned back everyone seeking to enter the auditorium with a pop-bottle in his hand. No one not wearing a "convention servant" ribbon is permitted within 50 feet of the platform.
