Correctable Error

[TGR]

Rookie,
You wrote :"Do you clear the lanes and have A1 shoot his second free throw? Then line everybody up for A2's Double Bonus shots with play resuming from there?" The answers to your questions are Yes and Yes.
What the official in your organization told you is false. See 2.10.4 & 5.
Article 4:...If the error is a free throw by the wrong player or at the wrong basket, or the awarding of an unmerited free throw, the free throw and the activity during it, other than unsportsmanlike, flagrant, intentional or technical fouls, shall be canceled.
**This rule does not apply to your situation**
Article 5:...Points scored, consumed time and additional activity, which may occur prior to the recognition of an error, shall not be nullified...
**This rule does apply to your situation**
