Throw in violation, or legal play?

The play in question is after a made basket when the offense throws a pass to another teammate who is also oob on the other side of the key. Can the defense reach through and deflect this pass or would this be a technical foul? I believe it is a smart and legal play by the defense since the ball was released by the thrower. Others disagree in saying that this is not released on the throw in pass. Nothing in case book that I could find, although I only looked in the rules referenced above and their related case plays.

All you need to know in this case. It was not a throw-in pass. So, the player reached over prior to the throw-in pass being released.
