No, I meant Mexico. As what was needed to get to Cuba apparently what Oswald offered was good enough because the Cuban government granted him a visa. You want to believe there was an Oswald impostor that's your business but if a show is what you're looking for the actual Oswald visit was a pretty good show in and of itself. BTW, I don't see what purpose it would serve to have an Oswald impostor at the Cuban and Soviet consulates. Who's interest were served by coming up with this ruse?
And an impostor that, according to the Cuban and Soviet personnel, made quite a scene. Duran and Azcue said Oswald raised a ruckus and had to be physically escorted out of the building. Azcue told him, "The Revolution doesn't need people like you."
Then this impostor goes to the Soviet Embassy and is, according to the KGB officers/Soviet Embassy staffers, hysterical and emotional. He pulls out a revolver and says he needs it to protect himself. He says the "notorious FBI" is after him. Quite a scene.
But this supposedly Oswald fake is trying to get a visa? Two of them. Visas with photos and signatures on them. That he had to provide? And he pulls stunts like this?
The Soviet Embassy in Washington had photos of Oswald; he lived there for several years and all citizens were required to have internal passports. Plus they had his application for a visa with his photo. So this fake Oswald goes to get a visa and Washington approves it and sends it to Mexico City. When the Soviet officials receive it and look at the photo and see this impostor is just that: an impostor, what would happen?
This whole idea of faking him is completely illogical given what he had to do - provide photos, give his signatures - once there.
