Take the 2:43 minutes it takes to watch it and the depth of the problem in America really hits home. Stars like Beyoncé, Rihanna, Alicia Keys, Lenny and Zoe Kravitz, Pharell Williams, A$AP Rocky, Bono and Pink appear one by one, speaking directly to camera, alternating with images of some of the black men and women who have been killed by police in the US. Each celebrity states what each victim was doing at the time they were shot - from selling CDs in a carpark, as was the case for Alton Sterling, to carrying a toy gun in the park.

Alicia Keys headed up the project as part of her We Are Here movement, together with Mic. It's based on an article published on Mic, titled 23 Everyday Actions Punishable by Death if You're Black in America. We Are Here was established by Keys as a platform to campaign for social justice issues.
