Marshal,
A "bomb" in the sense it lost the studio and Capra nearly $1 Million, which was a hell of a lot of money back then as the entire budget for the film was only slightly above $3 Million. It failed miserably to earn back a figure coming close to covering its cost. (Given what it earned in Box Office and considering that amount was typically shared on a 50/50 basis between the theater and the studio, it really only earned about 1/2 of its cost back and that includes all the years up until 1974 when it became public domain.)
FM Poke, yep Hoover and his sycophants at the FBI saw what they wanted to see, much like in later years the FBI produced memos covering the "obscenity" in Louie, Louie (which actually contained no profanity). It brings to mind Jerry Falwell and his pronouncement of one of the telly-tubbies being gay.
Which likewise brings to mind the classic joke of the guy undergoing psychiatric treatment being given a "Rorschach" test. When he responds to every image by noting he sees tits, butts and female sexual organs the psychiatrist asks him: Don't you think you are perhaps a little obsessed with sex? The guy responds: Gee doc, I'm not the one going around showing a bunch of dirty pictures to people.
