Correct call or not:

Team A inbounding the ball. A1 called for illegal screen before the ball was inbounded (probably before the ball was released by the inbounder, if it matters. But I'm not sure on that issue)

Ref awards bonus free throw opportunity to Team B.

He very clearly (and after discussion with the other ref) was saying that because the ball was never inbounded team control was never obtained and therefore Team B should shoot. Another Dad (who is a ref) and I questioned the call at a timeout in a very respectful and polite manner. And he seemed very sure.

Was he correct?

I wouldn't have thought so, but I'm not a rules wizard like you guys and gals in here - Just a fan of the game. He seemed clear on the rule - so no reason to doubt him.
