Violation or not?

[bseybs32]

Situation: Player A1 shooting a 2 shot foul. (Girls JV)

I admininster the ball to the shooter, A1 for the first of the 2 shot foul. A1 bounces the ball a couple of times, and then bounces it off her foot, and the ball goes rolling down the lane. A1 steps across the free throw line and retreives the ball.

My partner calls a lane violation. I agree with the call.

We cancel that attempt and I tell the players last shot play when the ball hits the iron.

After the game, a varsity official (there to watch the game)asks my partner why he called a violation stating he would have just let A1 reshoot the free throw. He also stated if team B coach says anything his reply would be "We will do the same for you." My problem with that is, what if Team B players don't commit the same violation the rest of the game. We just let Team A get away with the violation.

What are your opinions on this?
