Without the QA/QC protocols in place the incompetent could have numerous ways to screw up. However, with the QA/QC protocols that have been developed it is now very difficult to fudge Assay results (though there are some who are always cleaver enough to do what ever it takes) at the Lab. Thus, if there are inconsistencies, the knowledgeable Authorities will know the nature if the problem. Thus, if there was and hanky panky involved someone will have to pay the legally proper price. Otherwise, the Lab company simply looses all future business. Can be that simple! But when there is Skunk Odor around there likely is such a creature close by??? Old Joe
