This crazy person could of had a knife or even a gun...she stood close enough behind the priest to inflict some real damage..yet no man took it upon himself to protect that sanctuary and priest.

The woman (obviously unbalanced) quite possibly was known to the parishioners and, in particular, to the woman in the red top who eventually left her pew to intervene. The unbalanced woman, in fact, may have done similar things at other times while in this small church.
Seeing how carefully the woman in red proceeded, I believe the disrupting woman was known to her and perhaps others in this church as being harmless and not a threat to anyone. Yet, she needed to be stopped and I would say that the woman in red exercised good control while still getting the job done.
