My pleasure. Nah you have a point about that, sorry.

Not Awardable

A handball should not be awarded if a player is ruled to have handled the ball accidentally. This refers to a player either attempting to protect himself from injury, for example by placing the hands in front of the face and then being hit by the ball, or a player being hit on the arm by the ball without moving towards the ball and without being able to move out of the way. An example might be a snap shot hitting the arm of a defender at point-blank range. However, if a player’s arm is in an unnatural position, for example outstretched or above their head, then a foul should be awarded whether accidental or not.

See your point would've been valid if only

was in there

Unfortunately for you and fortunately for me this part is also in it

However, if a player’s arm is in an unnatural position, for example outstretched or above their head, then a foul should be awarded whether accidental or not.

The arm was clearly outstretched, which in turn makes it a textbook penalty.
