It’s Martin Luther King Jr. Day, and Philadelphia is busy remembering his legacy. City and state officials like Mayor Michael Nutter, Council President Darrell Clarke and D.A. Seth Williams have been honoring the memory of King through speeches, social media and service.

“Our lives begin to end the day we become silent about things that matter” – MLK Jr.,

Indifference + inaction are the enemies of #justice. Let’s vow to do more to uphold his legacy #MLKDay2015 — Darrell Clarke (@Darrell_Clarke) January 19, 2015

On MLK Day of service, let’s commit to nonviolence, voting and community engagement. Peaceful protest respects the life and legacy of MLK.
