What biased nonsense. The shot half-arm-guy had a pistol in his half-arm; one of the dead was using his skateboard in a deadly manner.
A barf-alert is appropriate for this rag of an article.
Which, given his prior attack on the AR-15 wielder, he already had his handgun in that hand. I.e., the AR-15 wielder acted in self-defense at that point. Though why the BLM dude didn't use it immediately, and intead jumped on the AR-15 guy from behind, is a good question. Maybe he was trying not to use deadly force. Maybe he just wasn't thinking. We'll probably find out.
