He didn't have a gun when he was shot, what are you talking about? He didn't even have a gun in his hand. Or you mean that you can accidentally shoot somebody who had a gun, at some point in the past?
(Hence I'm calling it an accident, where the police officer may be at fault. Though, other commentators saying it was cold blooded, a death sentence, deliberate, etc. is not true. Nor is generalizing this particular situation to changes in government type. These people really want to portray their political opponent as bad as they possibly can.)
I need you to read this and really think about the words.
You should watch the video. While seem to be an accident, a way to avoid it would have just been not bring a gun in the first place nor engage physically with law enforcement.
These actions in general to restrict law enforcement to do their job isn't helping either. Protest in front of government buildings, not follow police around.
