Wait untill you learn about how HW was in Dallas the day JFK was assasinated, placed a misleading/red herring 'tip' call to the FBI, and in every subsequent interview in all of his life, couldn't remember exactly where he was or what he did that day... a day that, like 9/11, basically everyone who was older than maybe 10ish remembers in decent detail where they were and what they were doing when they first heard the news.

Oh did I mention that prior to that, his import/export/offshore drilling company in the Gulf of Mexico was used to funnel arms to the group that would do the Bay of Pigs Invasion?

Entirely seriously: George HW Bush was substantially involved in the assasination of JFK.

Also worth mentioning:

HW's dad, Prescott Bush... yeah, he ran a bank that got shut down during WW2 for laundering money to the actual Nazis.

Prescott Bush literally financed the Nazi party's rise to power.

Original outlet that broke the story in modern times:

Somewhat hilariously, even Fox News reported on this.

As did Haaretz:

I know but the original quote is who killed who, so figured accuracy beats grammar.

"Whom" is on its way out because there is no loss of understanding whatsoever if you just say "who" instead.
