Free throw antics - any call?

[JoeT]

I was watching (not working, thankfully) one of the Illinois HS girls class AA sectional final games last night. The sectional finals winners advance to the final field of 16 teams who will compete for the state championship, so this game is huge and both teams are excellent.

The game included plenty of spirited fan participation in a packed college (DIII) gym. It was LOUD.

Situation with about 8 seconds left (my estimate; I don't recall exactly). Score is 44-44:

A1 is at the line preparing to shoot 2. She has not yet received the ball from the official, but all players are in place and ready to go. Team B's fan section is shouting loudly. B2 is positioned on the lane with her back to B's fans. She turns around to face them and makes a grand gesture with both arms for them to cheer more loudly. The volume doubles. In response A1 (who still does not have the ball) faces A's fans and does the same. She had a look like, "fine, you want it loud, then let's get loud!" Volume increases accordingly. B2 repeats her gesture for good measure.

I'll let you know how it turned out in a bit, but I'm interested to hear your thoughts on this. Do you say or do anything here?
