Problem is not only with things that test, but with unethical fitting and injections of "naturally ocurring" substances, as was the case a few years back at Denver. While carcasses (I think 17 out of 35 sale qualifiers) were found with all kinds of injection sites all down their topline, nothing tested. Not to worry, everyone still signs the "ethical treatment of animals" paperwork anyway, still should be kicked out, no questions asked, jmo.
