The FBI had been tracking Oswald for years. The FBI agent in Dallas knew plenty about him from the very first second his name was mentioned. He had just visited his wife. No great mystery. They didn't even need a "telephone to communicate long distance" LOL. The agent was there.
You're talking about Hosty, right? The same guy who destroyed Oswald's note.....
And as far as tracking Oswald is concerned, did they know he was in Mexico in the weeks prior to the assassination? No, they didn't.
Did they know Oswald had bought a revolver and a rifle? No, they didn't
What they did know was that Oswald was in jail in New Orleans, because they send an agent to see him there, at his request. That's some "tracking".
The information the DPD had early on, simply couldn't have come from one FBI agent.
They didn't even need a "telephone to communicate long distance" LOL. The agent was there.Really, genius... so their entire investigation after the fact was a waste of time?.... I mean, when "the agent was there" LOL
