I was very good friends with Gayle Geraci back in the 1960s and early 1970s.
Gayle Geraci was the younger sister of Philip "Flip" Geraci. We all lived in the New Orleans suburb of Metairie.
Flip Geraci was just an idealistic kid back in the summer of 1963, when -- while goofing around Canal Street (or was it Camp Street) one day, he stumbled upon a group that called themselves "Fair Play for Cuba." Flip was studying Spanish in school (he was about 14 or 15 when this all happened), and he was a really naive, idealistic (but nice) guy. So he stops and talks with them for a long while, and they talk him into raising some money for their group. So I think he raised a small sum -- maybe 10 bux or something (would be around 100 bux in todays dollars) -- for their cause. But I don't really think he even understood what the group was about, honestly.
Anyway, because he raised some money for them, he got "on their books," so to speak.
A few months went by, then on Nov 22, 1963 over in Dallas, TX, another guy that was associated with the Fair Play for Cuba group -- a man named Lee Harvey Oswald -- ended up getting arrested for killing President Kennedy. (I am NOT going to speculate here, whether I believe Oswald actually killed the President or not.)
FBI investigators swooped down on the Fair Play for Cuba group, seizing their books, and found that Flip had raised a small sum of money for the group a few months before.
So they pulled Flip (and his mother, since Flip was a minor) in for an interview. Flip didn't know anything, and the FBI interviewers soon realized they were dealing with a young kid who didn't have a clue.
Nonetheless, a few years later when the 24 volume Warren Report was finally published, the entire transcript of the FBI's interview with Flip Geraci and his mother is included in that report, verbatim.
