Eyebrows actually contribute a lot to one's facial identity. In one study, removing eyebrows from an image caused a higher rate of failure of recognition of celebrities then removing their eyes. You can read about it here:
It is also assumed that eyebrows have the functional purpose of soaking up sweat when we're sweating from our brow, keeping the sweat from rolling down into our eyes.
The idea that James Bookhout's eyebrows were actually shaped like that is untenable. I've been looking at images to see if I can find anything close to it, and I can't. Eyebrows just aren't made that way. They come as either a rather smooth arch or they are relatively straight. What we're seeing above is a sideways s.
These are all famous actors, but they are representative of men everywhere when it comes to eyebrows.
So, consider the situation when it comes to Bookhout. There are no recognized, acknowledged images of him from the assassination except for phony ones. The only real images of him are the ones from his young adulthood. And they doctored those images as well, giving him flamboyant eyebrows to change his look. What does it mean that they did that?
It means that it is a smoking gun, a smoking gun that Bookhout was Oswald's shooter, and they just don't want anyone to get a good look at him.
James Bookhout was the shooter of Lee Harvey Oswald, and it is another dirty little secret of the JFK assassination.
