Many of the volunteers have recounted that the summer was one of the defining periods of their lives. They had trouble readjusting to life outside Mississippi. They came with a positive image of the government, but the events of the Freedom Summer upset this simplistic distinction between 'good guys' and 'bad guys'. They saw that those two ideas were linked together. They experienced such lawlessness that they became critical toward American society and federal agencies, like the FBI. Most of the volunteers became politicized in Mississippi. They left intent on carrying on the fight in the North. After that summer, many Christians faced a religious crisis. Personal transformation of volunteers led to social changes. It increased student activity in the civil rights movement. These students also played a role later in the resurgence of leftist activism in the United States.
