Just two things for right now.

1-- Some years ago I was told by the guy who had been head of the group that regulates racing in a very major racing state that they hadn't trusted their lab, so they loaded some samples with illegal drugs to see what happened. They got back no positives, and ended up switching labs.

2-- A couple of years ago I banned someone from this board who took the position that based on their professional expertise they could say that if people were cheating they would have been caught by testing. I knew 1, above, at that time, so I knew that was total horses--t. And that was aside from what I and lots of others could tell from looking at figures, and aside from what Allday had admitted to publicly, and aside from what I knew from others involved in trying to catch people who were cheating.
