If it was an AP throw in, the arrows stays with the inbounding team.
Agreed. If the defender had to reach through the plane, it would be a technical. That's one of those rules that has never made sense to me. If you reach over and swipe at the ball, it is called an intentional foul, yet if you actually contact the ball, it is a worse penalty, a tech.
