This is like any topic -- I expect statements and claims and conclusions to have facts and data and controlled observations supporting them. This is important in all domains, not just anti-doping.
There is also a question of justice. Principles of "strict liability" and "guilty until proven innocent" is great for quick and cheap convictions, but it puts innocent athletes at a great disadvantage. I share Tygart's expressed concerns about changes in the 2015 code. He is better positioned to lobby for change, and ultimately, it is athletes who are the ones taking the risk, and it should be athlete representatives shaping that discussion.
Aggressive prosecution under the current system can result in many innocent athletes being banned, which hurts the sport without improving anti-doping. Recall all the nandrolone bans in Kenya -- a nation that doesn't routinely castrate its pigs. Which of these athletes can afford a 5 to 6 figure defense?
Apparently a lot of people here care to say that it was intentional. The fact remains that intent wasn't established to any legal standard.
You are not correct in assuming that my position is that if an athlete tests positive for a banned substance & they claim it was from a contaminated food substance, beverage, supplement, etc, - they should not receive a ban. This has to be evaluated on a case by case basis. I do think that athletes should get some benefit of the doubt, when there are low amounts of a banned substance consistent with meat consumption. It doesn't seem correct that athletes like Lawson have to become experts in the beef industry for eating a Teriyaki bowl, that Getzmann has to be lucky to test his medication which was contaminated within and below the national guidelines, but still detected by anti-doping labs, that Asinga has to become an expert on gummy bear manufacturing and lot numbers, and that athletes who are mostly at or below poverty level even in rich countries, must spend 5-6 figures on a defense, while serving a 1-year suspension before they are cleared to compete again.
