I'll give it a shot:
A2's basket counts.
Charge a technical foul to A1 for deliberately taking a FT to which he was not entitled.
Give A3 two FTs with the lane cleared.
B gets two technical foul FTs and the subsequent throw-in at the division line.
You and your partner(s) spend the rest of the game preparing for the a$$-chewing you should receive from your assignor.
