Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

Consider how stupid it was to have a shot from the front if Oswald was supposed to be the lone gunman. How were they going to explain that?  Why shoot from the front at all? How did they intend to attribute a shot from the front to someone behind? And remember that the Single Bullet Theory was a creation of Arlen Spectre months later: April 1964. It didn't exist on 11/22/63, and there's no reason to think anybody conjured it up beforehand. 

The lone gunman scenario could not include a shot from the front. Period.  So, why did they shoot him from the front? And since they were also shooting him from the rear, how did they expect to attribute all that shooting to one gunman? 

It seems likely that the plan to kill JFK arose within the anti-Castro/Bay of Pigs covert CIA operation: William Harvey, David Atlee Phillips, David Sanchez Morales. They went to Dulles, and Dulles went to Johnson. I don't think it started with Johnson, but he was glad to come aboard. But, in the beginning, they may have been thinking of it as a false flag operation to blame on Castro so that they could invade Cuba. So, if the ultimate blame was going to be on Castro, it didn't have to be a lone gunman. 

But, I think what happened is that as it got closer and closer, Johnson rose higher and higher in authority. And he is the one who decided to forget about framing Castro. All LBJ cared about was getting rid of JFK. 

I think they hoped that the very first shot from the Dal-Tex building would do the job. Their forward shooters were a fail-safe.  They wren't going to let JFK get out of Dealey Plaza alive, and if they had to shoot him from the front to kill him, they would. Then afterwards, they could just say there was a shooter on the triple overpass, and he got clean away like a fart in a high wind. 

But, Johnson and his men took over the script, and even though there was a shot from the front, they wanted it to be a lone gunman. But, they weren't in contact with the crack team of photo alterers who were doing their thing. Hence, there is a hole in the windshield of the limo which you can see in the Altgens photo.

The illogic rests with having forward shooters in a lone-gunman-from-the-rear scenario, but neither I, nor anyone else, can explain that. But regardless, I say the Altgens photo came before the hit.
