So you said that someone else had to be there to witness and divulge 
the event in a later post (that I can't find right now), and the 
question became: but who was it? 

US Pb PoA (p361): "Like father, like son, Potter! . . . You'd have 
died like your father, too arrogant to believe you might be mistaken 
in Black -- now get out of the way, or I will make you. . . ." -Snape

Now, Snape could have heard from other DEs or surmised that James 
didn't believe that Sirius could betray them, but it sounds like 
Snape *knew* that James believed Sirius innocent *until he died,* 
perhaps because Snape had seen it with his own eyes.
