As much as we don't like certain situations (i.e. running up the score), we as officials can only apply the rules as they're written, not based on some emotional basis of "right or wrong"
So, if in your judgement, the defender has obstructed the vision of the shooter WITHOUT contact, it is a legal play.
Now, if "in your judgement" contact WAS made, however minimal
(see my first post above), then call the shooting foul.
To me, this is similar to when B1 flops on the ol' block/charge WITHOUT contact. I almost always call that a block, mostly to protect A1 on landing (safety issue), but also to demonstrate that that type of "defense" won't be tolerated.
If B1 says "I didn't touch him", I reply, "then why did you flop?". They get the idea pretty quick and more often than not, stop flopping
If a coach questions it, my stock reply is "Your players will get the same call on the other end, coach" even though I know the other team doesn't do it.
For what its worth...that's what I would do
