Yesterday was the 50th anniversary of Bloody Sunday, the day Sheriff Jim Clark and his posse beat MLK and 600 non-violent marchers mercilessly in Selma Alabama. Dr. King and his followers were attempting to cross the Edmund Pettus Bridge on their way to Montgomery to protest voting rights abuses. The carnage of that day was horrific, but yesterday’s celebration was both joyous and solemn – a reminder of how far we’ve come. MLK was absent but his powerful presence energized President Obama and 70,000 fellow Americans who marched across the bridge to honor his legacy.
