Civil rights activist Reverend Jesse Jackson looks on outside the 16th Street Baptist Church in Birmingham, Alabama September 15, 2013. Fifty years ago, a Ku Klux Klan bomb went off at the 16th Street Baptist Church, killing four girls getting ready for Sunday School. The death of the four girls ignited a push to pass the Civil Rights Act of 1964, which bans discrimination on the basis of race, color, religion, sex or national origin.
