Samuel L. Jackson urges celebs of Ice Bucket Challenge to protest against 'racist police'

Samuel L. Jackson has recently challenged celebs, who pour ice buckets over their head in order to support a cause, to sing a protest song against "racist police."

Thousands of Americans took to the streets to protest police brutality and 65-year-old actor urged his fellow artists to contribute their voices to the popular movement, the Verge reported.

Jackson sang the lines: "I can hear my neighbor crying 'I can't breathe,' now I'm in the struggle and I can't leave, calling out the violence of the racist police. We ain't gonna stop till people are free.
