Sparky, I can't find the photo you speak about, either. But, the following link has an account of that photo being taken.

C. H. Lyon tells us: “The attendants did their work well. A couple of the more obstreperous Coughlinites were rapped on the head with a cane, and all of them were unceremoniously hurled down the ramps and out of the auditorium. One of the Coughlinites rated some publicity in a daily tabloid the next morning, as they printed a picture of him with his head wrapped, as with a turban.”
And, an account of another photo - a police officer:
Mob violence also erupted during the 1942 assembly in Klamath Falls, Oregon. According to Don Milford, mobsters cut the telephone wires bringing a discourse from another convention city, but a brother having a copy of the talk immediately took over and the program went on. Finally, the mob broke into the hall. The Witnesses defended themselves and when the door was closed again, one attacker—“a large powerful man”—lay unconscious inside the building. He was a police officer and his picture was taken with his badge alongside his face. “We called the Red Cross,” says Brother Milford, “and they sent in two women with a stretcher and took him out. He was later heard to say, ‘I didn’t think they would fight.’” The police refused to aid the Witnesses, and it was over four hours before the mob was dispersed by the state militia.
