I just went back and looked at this.....AGAIN.
Notice in this photo that there are TWO "tufts of hair. The one that looks to be the entrance wound (or most matches the tuft that is supposedly the "exit" wound) is BELOW the one that we see on the video.
Here's the link to the video. Notice the tuft you see here is NOT the "entrance" wound.
