On Saturday — the same day thousands of demonstrators marched the streets of major cities like New York City and Washington D.C. to protest recent police brutality — actor Samuel L. Jackson posted a video on his Facebook page, challenging "all the celebrities out there who poured ice water on your head" to sing the "we ain't gonna stop, till people are free" song.
The lyrics, which are posted below, call out the "violence of the racist police," mirroring Eric Garner's last words "I can't breathe."
Watch the video:
I can hear my neighbor cryin' 'I can't breathe' / Now I'm in the struggle and I can't leave. / Callin' out the violence of the racist police. / We ain't gonna stop, till people are free. / We ain't gonna stop, till people are free
