A woman weeps outside historic Mother Emanuel African Methodist Episcopal Church, June 19, 2015, in Charleston, S.C., after Dylann Roof, murdered nine people there during a prayer meeting. Now, survivors and families of the victims are asking a court to allow them to sue the federal government over what they say was a failed background check of Roof, allowing him to get the gun used in the shooting.

Survivors and families of the nine people murdered at their South Carolina church when white supremacist Dylann Roof riddled them with bullets four years ago want the federal government to pay for the role they say it played in their loved ones’ deaths.

Lawyers for the group say a federal background check should have prevented Roof from being able to get his hands on the gun he used in the attack.
