This is the story of Eddie Cortez who survived an electrical accident back in 2006 when he was electrocuted with 7200 volts at least...twice.
His upper body suffered the effects of the shock, except for the brown scapular of Mt. Carmel he was wearing the day of the accident. Cortez says the scapular saved his life.
After reading this story, I think that is proof enough of the maternal protection of Our Lady to those who would faithfully wear her badge.
