Basket Interference?

The following shall result in an indirect technical foul being charged to a team or player:
Art. 14. Intentionally slapping or striking the backboard or causing either the backboard or ring to vibrate while the ball is in flight during a try, or while the ball is touching the backboard, is on or in the basket or in the cylinder.
The way I read this (because of the "or"s), it's a T if an unintentional slap causes vibration while the ball is on the basket or in the cylinder.

The way I read that is it is a T when:

Art. 14. Intentionally slapping or striking the backboard or [intentionally] causing either the backboard or ring to vibrate while the ball is in flight during a try, or while the ball is touching the backboard, is on or in the basket or in the cylinder.

Therefore, no T when it is unintentional.

And, there is no case where you must call something (if no rule is being violated).
