Everyone is reacting in their own personal way to the police-involved shooting deaths of Alton Sterling and Philando Castile. Macklemore is no different.

The Seattle rapper, who is known to portray himself as an ally to the African American community, took to Instagram yesterday afternoon (July 6, which would’ve been before news of Castile’s death broke) and asked his fellow race to think of things differently if they’re in the business of unconditionally blaming black victims of police shootings.

“How many times can we watch a family at a press conference in hysterics over the killing of their loved one? Murdered by those that have been assigned to protect us,” he captioned in the post featuring the now widely-circulated pic of Alton Sterling. “What do we do in times like these? It's a question for everyone, but specifically white people. The systematic oppression that enables a murder like this, will be corrected once white people care enough to change it. Alton Sterling didn't create this problem. This is hundreds of years of conditioning.”

After explaining his beliefs on police brutality and the history of violence against Blacks by law enforcement, Mack made a few demands of whites, and he’s very clear as to how he believes they can help.

“I often don't know what to do during these moments,” he continued. “It becomes easier to vent on social media than to take direct action. Here's a couple things I've gotten hip to in the last two years. 1: Financially support Black-led organizations. Put your resources behind people of color that are at the forefront of the movement 2: Do a People's Institute "Undoing racism" training. One of the most eye opening and important tools to understanding our past in relation to the work that needs to be done. The website is http://www.pisab.org 3: Have conversations about race. In real life. With people that look like you and people that don't. RIP #altonsterling.”

Alton Sterling was shot multiple times in his chest after police pinned him down and discovered he had a firearm in the back pocket of his pants. Philando Castile was shot and eventually died after police believed that the identification he was reaching for inside of his car (which they require he brandish) was a firearm.
