booooo'd out of the gym

NFHS HS. I don't have my book with me, but this call is killing me, please help!

Made a call tonight which I am sure I read in the Rules Book. I thought staff was gonna have to call the police.

Team A is down 1 when B1 fouls A1 driving to the basket. I am the T. 2.2 seconds left on the clock. Two shots for A1, 1st FT is good. Here is where it gets ugly. As the shot is released, my P in the C blows his whistle for a violation on the shooter. As the ball is on the rim in the cylinder, B from the low block, jumps and knocks the ball off the rim. Instinctively, I blow my whistle. I called goaltending on B. You know the rest, basket is good, inbounded by B, long shot by B no good, game over. My P's acted like I was infected with some kind of virus.

The call makes no sense to me now that I think about it!

The ball was blown dead on the violation by the shooter, how can there be goaltending?

Let me stop before I go crazy!

HELP, PLEASE!
