The 1963 church bombing in Birmingham, Alabama, which resulted in the death of four young girls, has become one of the prominent tragedies of the civil rights area. The bombing and its significance has inspired many writers, musician, and even filmmaker Spike Lee, who created a documentary called 4 Little Girls.

In 2001, KKK members Thomas E. Blanton Jr., Robert Chambliss and Bobby Frank Cherry were convicted of the Sixteenth Baptist Church Street Baptist Church bombing that killed Addie Mae Collins, Cynthia Wesley, Carole Robertson and Carol Denise McNair.

Both Cherry and Chambliss have died in jail. However, Blanton is set to appear before a parole board on August 3.

When the public was made aware of his possible parole, many felt that they needed to take action against him. Mavis Austin of Colorado set up a petition on change.org to keep Blanton behind bars. So far, the petition is just a few thousand signatures short of the 50,000 needed to get a response.

U.S. Attorney Doug Jones also objects to the possible parole of Blanton. Jones, along with the family members of the little girls, plans to attend the hearing.

"He has shown no remorse. He's shown no acceptance of responsibility," Jones said. "He has not reached out to the families or the community to show acceptance of responsibility. I think that's an important part of parole consideration and it's completely lacking in this case."
