I think it's entirely possible the scabs yelled fire. It's even possible they held the door. As much as I dislike scabs and strikebreakers, and as much as I detest robber barons who try to crush unions, I still think Woody, God rest his soul, did a dirty thing by convicting the thugs with manufactured evidence. By the time Woody wrote his song, he definitely had the information about the doors opening inward. Do the ends justify the means? There are plenty of nasty things to say about scabs without making up lies, and carving them in musical stone for future generations to believe. It's too late to convince Woody, but there are other songwriters in this forum. I hope they will have the decency to qualify their lyrics, or else adopt an allegorical event that doesn't involve real people.
