I couldn't understand why congress cared about the issue, but I heard one congressman who was explaining why - some of his reasons were that baseball enjoys antitrust protection, and that many of the teams play in publicly funded/owned stadiums, making it a business where the general public (and thus, the government) has more of a stake in keeping it honest. I personally think they just want to see their mugs on TV.
Because it distracts the citizens from the economy, the war in Iraq, the upcoming war in Iran, the gross incompetence of the CIA, the fact that Osama Bin Laden is still at large, the horrors of Guantanamo, the gutting of the Constitution, the looting of taxpayer pocketbooks done by Halliburton, Enron, and other Administration cronies, and the various other criminal enterprises of the Bush II presidency.
OK. My opinion is that they aren't doing this to distract anyone from anything, but because they know they can get ESPN TV time and some kind of ridiculous "what about the children?" credit from the kind of people who give that out.
There is, I suppose, some vague element of fraud/deception that could be argued with respect to drug use in sport, but I figure it's largely a vote-gathering exercise.
And Al Fayed is completely barking mad, but I dunno, he could be on to something - Prince Philip as secret ruler of, well, just about everything. And his secret family name ends in "Frankenstein". Well, what more proof do you need? And I never liked that Tony Blair.
