FT double violation

[thumpferee]

nfhs

I am the L. A1 shooting 1st of 1-1. B1 steps in the lane on the release. I signal for the delayed whistle, before the ball hits, my p in the C whistles for a violation on the shooter. Ball goes in.

Double violation, cancel shot, team B's ball?

Re-shoot 1st of 1-1 due to the violation on B which occured first?

Rules Book and Case Book didn't exactly cover this stitch from what I found. Then again, I have last years rule book.

Thanks!
