The eerie silence was broken only by the sound of scuffling feet as marchers approached the Edmund Pettus Bridge in Selma, Alabama. The mood was sober. Hundreds of men, women, and children had been protesting in Selma for weeks to win black Americans the right to vote. Theyd been threatened. Been arrested. Jailed. This march was likely to end in violence, yet they went anyway. But when state troopers attacked with billy clubs and tear gas, the brute force was a shock. Many were injured, including children.
