They should have checked more places.
Hoover foamed at the mouth regards commies.
Realize, the FBI had a major commie threat during the aftermath of the Great Depression and in the formation years of the FBI. Then came the 50s and the big red scare (which back then was real, unlike this Ukraine farce today).
If Hoover were alive today to see what sort of faggots and commies are in the leadership of his organization, he’d jump from his HQs.
And no, Hoover was not a cross dressing closet homo. That’s Hollywood selling the idea that inside of every homophobe is a closet homo. Hollywood creates there own “version” of history, religion, war... which usually fits an ultra liberal agenda.
