Backcourt questions

[moref]

1. A1 has the ball and then attempts a pass to A2 in Team A's frontcourt.Before the pass to A2 gets there B1 deflects the ball and then the ball touches A2 before going into backcourt therefore it is a backcourt violation if A2 goes backcourt to get it. T or F
I have seen this called both ways.I want to know if anyone else has seen this called both ways.I say it is a violation because Team A had team control still. Now on a throw in Team A's frontcourt and the ball deflects off of one of team A's players then they may go backcourt to get it without a violation because there is no team control during a throw in.This is high school rules only.(NFHS)I am not giving a rules meeting here I am just asking.
