Chief Keef took to Twitter after watching a recent video of San Francisco officers repeatedly shooting a knife-wielding suspect, and the Chicago emcee said he believes “We need to kill all Law Enforcement!” He added, “Y’all down? F*** it! Time to make the world end.”

The post has since been deleted, which features the shocked rapper writing, “Why did they shoot that little boy down like that? On the side walk! I couldn’t even watch it.” Keef also addressed President Obama in the situation, “Aye @BarackObama Man What U Gonna Do About This Man? For real I don’t like it I didn’t say anything about anything else but this isn’t right.”
