If so, here's my answer:

I don't have my rulebook in front of me, but I'll try to explain it how I remember:

If an opposing player does a lane violation, you have a delayed lane violation. Any other infractions in the lane (any of the other 5 players or less occupying a lane space) is ignored.

Now, if A1 is shooting, and B1 in the lane steps in. You still have a delayed lane violation. But if the shooter or a teammate behind the shooter violates by stepping over the foul lane (shooter) or 3-point lane (teammates), then ball is dead for a double violation.

Any time any of the teammates of the shooter, or the shooter him/herself violates, ball is immediately dead.

The OP is refering to before the ball is at the disposal of the shooter.
