Monday marks four years since 12 members of the historically black Emanuel African Methodist Episcopal Church in Charleston, South Carolina, welcomed a young white man to join their bible study group. When their eyes shut for a closing prayer, he pulled out a Glock pistol and fired 77 rounds, killing nine people. In the days and weeks that followed, the nation learned about the lives of the people killed in the racially motivated massacre. Families of some victims told the shooter they forgave him. Amid an outpouring of support for survivors, South Carolina legislators debated and voted to remove the Confederate flag from the South Carolina State House.
