JFK Video Post Assignment

1. I learned that when you shot a bullet it can go through two people. I also learned that when a bullet is shot it can yaw which means it goes straight and then all of a sudden it starts to move and like tumble. I also learned that a gun called a Carcano has a full metal jacket and it also has a cylindrical shape, with straight sides and no taper or sharp point.
2. Some of the things they used to reconstruct the assassination was the pine board test, They shot a bullet to see how far it could go into the pine boards, this is one of the oldest ballistic tests around. Then to simulate human tissue they used ballistic gelatin and ballistic soap which both have the same density and resistance to penetration. When the gelatin is shot the bullet path opens and then collapses when the soap is shot it freezes the path of the bullet so you can see it. 
3. Based on science, I believe there was only one shooter and that the bullet went through both JFK and Governor Connally. I also don't believe that he was shot in the back of the head, how could someone be shot in the back of the head and then there head flies backwards it just doesn't make sense to me.
