No, the induction is an honor. Its totally optional.
The argument that because we can't get Selig or the writers or the others who had a part in this, we should HONOR Clemens and Bonds (and the others...), doesn't make sense to me.
And yes, people who played a big part in the phenomenon and the cover up will get away. But maybe someone will think twice about cheating or covering up in the future.
People forget that the Black Sox Eight were acquitted in a court of law. The participation of several in the fix was debatable. And there was a cover-up that supposedly involved many others (yes, writers too).
Judge Landis kicked them all out of baseball. He didn't get all the players who threw games before or after. He didn't get the writers or the owners who covered up all the cheating. By all accounts, gambling was an epidemic then much like steroids were recently (steroids may still be).
Landis didn't get all the cheaters and he may have even banished an "innocent" or two and/or a "not totally guilty" one. But he was right.
If all we get from the steroid cheating epidemic is Bonds and Clemens looking at the HOF from the outside in, it won't be much at all.
But the alternative is nothing.
