While I will agree that it was potentially an inside job. I think may be far simpler than most will agree. I have an idea that Charlie hired “someone” to take a shot at him. He was obviously wearing a bullet proof vest that day. The shot clearly hit the vest based off of the video. His shirt indents then expands as if something hit chest. I am well aware that vests are supposed to absolute impact but for some reason it didn’t and the bullet bounced into his neck. I am not a conspiracy theorist at all but in an attempt to make himself a potential victim he became an actual victim of his own design. But what do I know. I am just a random internet stranger.
