Celebrities are using their public platforms to speak out against police-involved shootings.

In the first week in July, two black men were killed in Louisiana and Minnesota just one day apart.

Alton Sterling, 37, was fatally shot in Baton Rouge on July 5 after cops responded to a call that Sterling had threatened someone with a gun. Philando Castile, 32, was shot dead by police during a traffic stop in St. Paul the next day.

Following the July shootings, actor and activist Jesse Williams posted a series of tweets, writing, "In the interest of time, would ye noble patriots please provide a list of infractions punishable by spontaneous public execution? Thanks! ...Upon receipt of this list, we'll return to our quarters and study up, eager to enjoy freedoms of white mass murders. #LIFEHACK...You chumps will NEVER provide this list... We see through you." At the 2016 BET Awards, Williams spoke out about racism in America and police brutality, saying, "[what] we've been doing is looking at the data and we know that police somehow manage to de-escalate, disarm and not kill white people every day. So what's going to happen is we are going to have equal rights and justice in our own country or we will restructure their function and ours." A Change.org petition called for him to be fired from the ABC show "Grey's Anatomy" on the grounds of racism for these comments, but show runner Shonda Rhimes stated she had no intention of removing him from the series.
