Rosa Parks being fingerprinted on February 22, 1956, by Lieutenant D.H. Lackey as one of the people indicted as leaders of the Montgomery bus boycott.

This was a few months after her arrest on December 1, 1955, for refusing to give up her seat to a white passenger on a segregated municipal bus in Montgomery, Alabama.
