Rafael Palmeiro--is he telling the truth??

Today, Palmeiro was tested positive for steroids. Just a few months prior to this, he testified to a congressional pannel saying that he could never have used steroids. Now he claims that he unintentionally took them. I guess some steroids can be found in protein supplements, so how many other times has he unintentionally taken them?? Why wouldn't you read the label very carefully before taking something like that? Maybe he is telling the truth. Why would he start/continue taking them now that they are really cracking down on them? And, if he isn't telling the truth, how come he is only suspended for 10 games? After all of this talk of steroids, shouldn't the punishment be harsher if he is indeed lying about it? I guess his punishment will be harsher, because if it comes out that he lied under oath, he has tougher times ahead of him. It would definately be a tragedy if he did end up intentionally taking them, because he just joined Hank Aaron, Willie Mays and Eddie Murray as the only players with 3,000 hits and 500 homers. I guess only time will tell.
