Living the Principle: Short Creek 1953
Just before dawn on July 26, 1953, more than 120 Arizona police officers descended on Short Creek in what then Gov. Howard Pyle called "a momentous police action against insurrection." They found residents of the polygamist community, who had been tipped off about the raid, gathered at the schoolhouse, singing. In days that followed, families were lined up outside their homes and photographed.
