Rule 9.1.1 Casebook play, Dribbling off foot on freethrow

[jritchie]

Just looking at this and wondering how many people try to blow the whistle and get the ball back to the shooter after they dribbled it off their foot or whatever they did to lose it, before they step across the line or before another player steps across the lane to retrieve the ball? Or do you just blow the whistle for the violation and take away the shot and if there is another shot, shot it or if not give the ball to the other team OOB.
