It's so rare, I thought, to find something actually in black and white that would seem to corroborate the story or would at least bolster the circumstantial evidence.

for this story.

Unrivaled, I think, is probably the word to use.

I think certainly in the Western Hemisphere, the CIA station in Mexico City in 1970 was the agency's largest operation, I think, outside of Saigon.

Obviously, the Vietnam War was going on at the time, a lot of efforts focused there.

But in terms of the Western Hemisphere,

Mexico was it.

And this is for a couple of reasons.

One is Cuba, right?

It's a useful place for keeping an eye on Cuba.

Cuba is still an obsession of the United States government and the CIA.

But number two is that it's a sort of happenstance of personality here.

The CIA station chief in Mexico City, right up until just before the World Cup, so summer of 1969, is a guy called Winston Scott.

And he's this legendary old boy.

He's one of the founding members of the CIA.

He's a real operator.
