It's a good question. If the deaths mounted around the posing platform as they have around the wrestling ring, Congress might get involved. The number of wrestling deaths is astounding over the last decade.
And I don't buy into the "Congress has better things to do" argument. This is what they are elected and paid to do. Since they can't stop the president from spending us into bankruptcy in Iraq, maybe they can stop steroids - or so goes the logic.....
