You have never been married have you? Oppie was a commie, his brother was a commie, Kitty was a commie, his friends were commies. Steve Nelson, a Yugoslav by the way, used to stop by, commie spy.
The FBI wire tapped these people.
If he was a spy I think Kitty would have had an "accident" and he would dissapear to some government bunker and be forced to work in total seclusion the OSS and the old CIA were not like their modern p***ified liberal equivalents they didn't f*** around.
