Legal play...
I had this happen last year. A fan (parent) sitting in the front row of a MS boys' game did not like me for not calling the violation. (His son was playing on the other team). The best part... he was wearing a zippered-referee shirt.
I politely leaned over to him during a dead ball and said, "since you're a referee, you should know that play is legal, rule ##-# on page ## of the rule book even says that it is legal." (At this point, I forget the exact rule citation, but I did at the time).
Coincidentally, this "official" has a copy of the NFHS rules book in his coat pocket in addition to his manual for the Friendly House Recreation League. He looked it up in the book, and discovered I was correct, and then did not hear a word from him the rest of the game.
