Your eyes see what the mind wants it to see. What you circle as being a gun is light illuminating the passenger's head as the car moves out the shadows.
It's taken me a while to realize it but trying to figure out all those mysteries, JFK, MLK, RFK, 9/11..... all that shit is a waste of your time. Be skeptical of anything the national news perpetuates or whatever, trust no one, but damn it all, spend your time doing what YOU want to do with your life, work hard, get money and build your own world. Everything else is a frivolous waste.
