Two issues

[MOFFICIAL]

I was at a game and the official bounced the ball to the free thrower and upon receiving the ball the free thrower noticed his own shoe was untied. The thrower set the ball down and began to tie his shoe. The official killed the play with his whistle and then had a couple of words with the thrower. Was there a violation that maybe wasn't called in this instance?

Second issue. The band and instruments are considered artificial noise makers and they shouldn't be banging drums or tooting horns during free throws or live action-am I correct?
