Equal rules don’t produce equal opportunity

Today marks the anniversary of Bloody Sunday. On this day in 1965, at the Edmund Pettus Bridge in Selma, Alabama, protesters — many of them women and children — were brutally attacked by police with tear gas, whips, clubs, and even horses. The marchers knew this would happen, and they marched anyway, sacrificing safety to secure something deemed more sacred: their voting rights.

The blood on that bridge forged the Voting Rights Act. But as we mark the anniversary of Bloody Sunday, a pending Supreme Court case, Louisiana v. Callais, threatens to squander the sacrifice.
