In just two days we've seen two innocent, unarmed black men shot dead by US police officers.
The first of whom was Alton Sterling, a Louisiana man who was pinned down by police and shot in the chest despite being completely immobile at the time shots were fired. The second was Philando Castile, a man who was shot dead in Minnesota after police officers pulled him over and asked to see his license.
Both deaths were filmed and uploaded to social media by witnesses, and naturally the backlash on Twitter has been strong. UK talent Stormzy is the latest to react. In a tweet captioned "Enough is enough," he posted this emotive image following the death of Castile.
Yesterday after graphic video of Sterling's death emerged, he posted this.
Over the pond, Drake penned an entire letter on how the video of Sterling made him feel "scared".
Nicki Minaj highlighted the lack of action against cops who commit brutality.
Zendaya, Will.I.Am and The Game also shared their outrage.
