Here's the thing. Oswald was recorded handing out these leaflets. Some may have had the Camp address, some may not. The Camp address is very well-known for being where a bunch of right wingers hung out, including Banister and Ferrie.
If Oswald was handing out leaflets and they were stamped Main Street and that address was linked to Commie left wingers, then it would surely bolster his Red sympathies. But that's not the way it happened. It was Camp Street, where Banister and Ferrie were known to haunt. Ferrie knew Oswald too as seen in the photo.
So again - big deal about whatever Stone did. It's the bigger picture that matters, Fred. You're just here trying to get more views for your blog and whatever else you're trying to sell.
