I hear you. This is YOUR movement. You are the young people who have organized the silent vigils and noisy demonstrations of thousands in Missouri, Berkeley, Boston, and New York.  It is you who have inspired a demographic rainbow of white, black, Asian and Latino in protests at state capitals and courthouses, chanting "Black lives matter".

You are tired of explaining the anger you feel about the killings of unarmed black men, about an unjust system that makes those killings more likely to happen, and tired of explaining that this is beyond the individual deaths of Ferguson’s Michael Brown and Staten Island’s Eric Garner.

This is your moment and you will not be denied by those elders who will not move out of the way to cede leadership. And when 10 thousand gathered two Saturdays ago for the Justice For All march in Washington D.C., you made that perfectly clear.

You did not wait to be invited to the stage. Some among you, tired of speeches from the old lions of the civil rights movement, demanded the microphone, while others chanted “let them speak” on your behalf.  Many called the public scuffle disrespectful, but 25 year old Johnetta Elzie answered that criticism this way: “I think it’s disrespectful that black people are being killed every 28 hours.”

You’ve been leading your way-- using social media to gather your troops, and alert the media. You have earned the right to be acknowledged as the engine of this new freedom train.

But, I remind you that you’ve couldn’t have gotten here without those elders who stood where you stand now. And when you let the world know the power of your numbers, and the strength of your commitment you took to the streets following a path created by those who marched where you march now. They know something about building and sustaining a movement. And, as anyone who has learned to drive knows, mastering driving lessons in a parking lot is a world away from what you know after years of being behind the wheel.

You are not kids, you know what’s at stake and what it will take to move a nation to change long held beliefs, deeply rooted customs, and outdated policies. Now that you are in charge I urge you to answer Governor Deval Patrick’s question—“what is it we’re trying to accomplish beyond disruption?”---by connecting the dots from marches to long-term strategy. But, don’t rush. I don’t think, as some do, that you must define all your goals right now.

The old hymn says "I believe I’ll run on to see what the end is going to be." Stay focused; continue doing the hard work of movement building, and the way forward will be revealed. Keep the faith.
