Continuation: don't want to be fouled, don't keep going

I'm not going to tackle the issue of the ridiculous continuation allowed in the NBA, which seems to be seeping into college basketball. I'm not going to get into the suspensions for physical play in the NBA playoffs, either, even though suspending Artest and Posey was the wrong decision. Last night, Raja Bell received a personal foul on a drive by Kobe Bryant. He also received a technical foul for knocking the ball out of Kobe's hands (or, possibly, fouling him again across the wrist) as Kobe continued to the basket and jumped in the air to shoot.

Bill Walton said something to the effect that when the whistle blows, the defense can't hit the offensive player because they don't want defensive guys taking free shots. I think Bill Walton is an idiot and shouldn't be on television. I'm sure many of you (if there are any readers) agree with me. If excessive contact occurs, call a technical. But, the play doesn't end when the whistle blows. This is NBA basketball, not football, where an offensive player can get an "and one" seconds after being fouled. If the offensive player can finish the play then the defense should be allowed to continue as well.
