I read that he had a gun.
We don’t know what happened. He was there by choice and thus is partially responsible for the consequences.
I read that not only did he not have a gun, but that he had his hands up and was complying, and that over 120 rounds were fired. That's a lot of lead for one old man. even though the early accounts said he had been hit six times.
Like I said, I'm waiting for the video.
