They did this today!  MLB did this 6 months ago.  

You know what I hate about all this "steroid scandal" is that the other sports, especially the media-darling NFL has skated through this without a scratch.

Sure we can look at McGwire and Bonds and see some muscle, but has anyone looked at NFL linemen?  These guys are biblically proportiioned giants.  Men 6-6, 350, 4% body fat, and can run 4.4 40's never existed in world history (outside of the WWF).  

If the world wants to take away HR records, let's revoke some NFL and NBA records too.  Or let's just say ALL sports have had dirty players (both offensive and defensive) and there is no conceivable way to subtract records.  Let's just throw out the bums that are still around and move on...
