Fair Rules ??

[APHP]

There was a little discussion in another post about rules being "fair". This one really gets me. A1's try is in the air when A2 swing arms/elbows excessively. No basket and B's ball for throw-in because of violation by A2. They go to the other end of court and B1 makes a try and B2 "contacts" A1 excessively with arms/elbows. The official rules personal foul. Count basket and give team A ball. I know that if contact is made it can be ruled personal, intentional or flagrant...but the basket is counted. So in the end, if contact is not made, cancel basket, if contact is made count basket.....SAY WHAT ??
