Herbert Randall was a 28-year-old professional photographer when he recruited to go to Hattiesburg, Mississippi to document Freedom Summer. He saw firsthand the danger the Freedom Summer volunteers were in, and felt compelled to share those images with the world. His work is chronicled in a book called "Faces of Freedom Summer". He says there will always be a need for the struggle to be documented.

"Freedom Summer" premieres June 24 on American Experience PBS.
